Air Rifle TUNING "HOW TO" w/PJ Clarke - Air Venturi - FX Airguns - How to Tune a PCP Airgun !! 

49:00 The AEAC universe is the center of airgun knowledge in my opinion. I'm into springers and low to mid level PCP's. I've learned immensely from Steve's efforts. Yes, I can dig the forums and spend lots of time talking one on one with the old timers, but as far as bang for the buck, you can't beat AEAC. Thanks for all your efforts Steve. Always looking forward to the next installment. Idec what brand or model is next to be featured. The knowledge is universal. I say it all the time... We're truly living the muscle car era of airgunning. What a time to be alive.

Positive update on the Avenger .22 regulator creep. I had three Avengers in a row that had extreme regulator leaks. They were almost identical in the amount and time it took them to creep. According to Air Venturi they were the barrel baffle models that went into the wood stock model but mine were plastic. After three creepers, I am very pleased to say my next Avenger has a stable regulator, nice trigger, and very accurate. This model is without the baffles and has the screw near the receiver that holds the barrel shroud in place. The creepers did not have the shroud screw. Steve, thanks for addressing regulator creep in this video. Looking forward to seeing more.

When I turned my air Venturi avenger bull pup in 25 I was setting it up for 33 grain slugs. I had the regulator pressure at 2800. I adjusted the hammer in 1/8 turn increments. In the end the hammer spring was turned in 1 1/8 turns to get the best accuracy. It was amazing at how small adjustments made such a big difference in performance.. Today I have a fx impact m3 compact in 30 caliber coming in. I’m going to shoot slugs in it. I’m glad you put a video up on this. Thank you for posting this video.

Yes, more of this with other industry user "experts" content providers, shooters, hunters, manufacturers on different subjects. Some history, some development, some best practices and techniques. Your content is fantastic, but, I think you talking with other shooters brings more perspective to the conversation. Good stuff both you and PJ.

Wow loved this! I really like the non knocking of different brands because it so is up to what you “want” to spend! And they all fling lead down range, but how far and fast and adjustable is in the $$$ you can afford and or want to spend. I’ve been along for the long ride. And watched many hours of video from you both and others! Glad you have it in you!! And thanks for your time! So much good info!!

Thanks for all these informative videos Steve! You are great at what you do, and I'm sure you consider yourself fortunate to have met all these great people in the industry and bring them to a place where we can all learn from each other.

Learned lots from you, tuned my Avenger so it shoots so good. What a perfect 1st PCP rifle. The Hammerspring was a big part of it, I shoot at 1900 psi, and vary the hammerspring based on ammo.🤘

Awsome information given out by two genuine people . Good to listen and see how we do things . Where as you start with the hammerspring low I start with it maxed . I then edge up the reg to be where I want to be . Backing off the hammerspring then until the speed just drops . Only reason is I find it slightly quicker . I also like how you mention you can get hung up on deviation and spread and get it very good but still have poor accuracy. This is so true and something people get to wrapped up on without actually testing all avenues due to poor numbers . Fantastic guys . I will watch the other half later 🔥

Thank you PJ for your service and all the knowledge you share with the community.

No waste of time in your channel and with such a guest invited. Very informative and clear. Thank you.

I watched the whole video! Thanks for your explanations with P.J. Worth the time to get a better understanding and education. Thank You both.

Thank you both for the awesome content and a big thanks to PJ for sharing his knowledge with us, much appreciated.

So much to talk about. Great first take! Informative. A lot of us listeners tune in for tips and know hows from u guys. Saves time and trouble and takes out the I wonders...some things you talked about i do not have another person to ask and its confirmation on things i was noticing. Thanks!!

One of the questions was sometimes it's nice to have a simple rifle that doesn't need hours of fiine tuning, thanks to Steve I bought 3 rifles over the years, Gamo Urban, FX Streamline and Air Venturi Avenger, all great rifles but my go to rifle for pesting , plinking is the Streamline, it's so consistent and reliable and it should do it's a $1000 rifle, it also makes my next pcp purchase difficult because it does what I want so well, but I'll probably watch another AEAC video and see another rifle I like.

Absolutely the best video I’ve seen to help me understand how to tune the M3 .357 I bought last week for hunting. Now all I have to do is hear how to use the valve adjuster knob to go along with the macro and micro adjusters. Thanks for this wealth of information and looking forward to the M3 tuning video. You both just got one more viewer👍

Thank you both ! Its always great to get input and hear different explanations on how things work . Sometimes all thats needed to get the meaning it the path of the words . MORE of these interviews please . Maby something around a bonfire with some drinks of choice . A little more let your hair down fun talking and some good stories . Merry Christmas all !

Hi Steve n PJ, thanks for the answer on my fx crown mk2, it has an amp reg but obviously now I know it shipped with an older Manual, I learned so much in the last 2.5 hour's I really need to say Thank you for all the hard work in making these video's, it was a real eye opener to me, take care, regards Mike

Thank you brother I learned so much from you and PJ today. This was so much more then just content, Maybe to coin a phrase? AEAC is where you get the wholetent we left the content behind!!!!

awesome to see two amazing people with a passion to learn and share...amazing video

Been snowed in for a day or two, so decided to treat myself to your video. So to start with thank you for a great informative video. You clarified many of the things I've been trying to figure out for some time. Many Thanks, Steve

Thanks Steve and PJ! Awesome video! Lots of great information! I’m new to PCP and I’ve been learning a lot from you guys.

This is best airgun video I can ever remember watching Steve/pj you two are killing it

just watched this video, and just wanted to say thank you both for all the knowledge and guidance youve provided, not just on this video but ALL videos...... you provide a very valuable service here so that we all can learn and stride to achieve "the perfect shot" time and again, once again, thank you, and please keep making videos :)

Thanks to both of you , really insightful.

I very much enjoyed this video. I'm glad I have marauders and don't have to worry about regulators. Just 3 things to adjust to tune perfectly.

Great video. Lots of good information. Thanks for taking the time. I am a newbie into the PCP world but amazed with its accuracy. I hope to be able to learn all the fine-tuning that you guys talk about. Definitely can be overwhelming at times.

Thanks Steve and I just subscribed to PJ, this was a great video, really informative 👍

I think it’s a great idea. Id enjoy it. Thanks PJ.

Very informative !! Thanks you guys 👍

THERE'S A DOPE STARTING AT 1:04:04, for Tuning Enthusiasts!! Love that PJ!!🤩 Steve, can't thank ya enough for bringing us this joint! Love ya both!!🤗

Steve thanks to you and PJ. You two and now Tyler are reason this young man of soon to be 75 years young are into pcp air rifles. Tyler thanks for making two guns I can purchase and learn how to tune. Thanks Steve and PJ for your videos on Avenger and Bullpup. All three of you are awesome. Thanks for caring about us little folks. Your videos I can't get enough of them. Watch over and over. GaryBlain in Texas

Very informative guys . Thank you.

Fantastic! Great information and points of view that make plain that this is a broad science and what we are learning will set the stage for future insights (that could appear radical now but won't be when that day comes).

Fantastic. Together is good. I've learned more. I follow both. Can't say enough from So. California. I will continue to follow and tell other friends. Thank you both

There’s some good info guys. Appreciate the time you two put into making this. Happy Holidays Guys

Thanks for the vid. Cannot wait for the M3 tune guide.

Man ! Amazing information , im defientely gonna play with my rega this weekend !!!!

As always a great video from AEAC. And will be subscribing to PJ’s channel. I’m a springer guy with no experience with the PCP world but if I ever do dabble with the dark side I feel I have an advantage because of the videos.

🔫😀I listen to the entire show while I was tuning my maverick. I’ve only had it for two weeks less than 300 pellets. I really enjoy both of your guises social media thank you for doing what you do it helps me:)

Great info. Yes to more of the same. Merry Christmas

Great video!!! Great information!!!

What a great Video....learned quite a few things ... 😀 Thanks .

Brilliant video! Can't wait for the m3 tuning guide. I'm rocking a compact 500 with a 600 barrel tuner ( meant for the the sub 12 standard m3) and trying to tune for the lighter 21 and 23grn slugs on a superior barrel in 22. Seems to favour the 218 H&ns, but weirdly at slower speeds (800fps) at 30m. Yet to try at 50/100, so not sure if they'll stabilise further out. Love. Your. Work.

still SIMPLY THE BEST.................BETTER THAN ALL THE REST..........Thanks, Steve! A Merry Christmas and a Happy New Year to you, Steve, your family and all of your viewers world-wide! Greetz from the Netherlands!

Awesome man loveed it yes do more

I think I was only about 5 mins in and knew that this was going to be good. Thanks for sharing.

Great information. Thanks dudes. Merry Christmas.

Thanks guys. Excellent information. God bless you both. Merry Christmas 🎅 🎄 🇺🇸

Very entertaining and informative. Thank you for another awesome video. Merry Christmas to you and yours!

Great video guys!

Awesome content guys ! Great collaboration between Steve and PJ. I have a Streamline and Dreamline that I both tuned because I love going through this process. I've ordered a Sekhmet gauge for the regulator of the dreamline because I see it as a great device to help me finetune the rifle and be able to go back to a previous tune. The Wika is good but just gives us a fairly rough idea of what the set pressure is.

Hi guys, like your focus! Everyday a school day! I'm shooting .177 out at 232 yards....Low power that is...Love it!

Great work Steve.keep it up,and happy holidays

This is the best video I have seen to learn from. I'm a perfectionist my self and appreciate perfection.

Some of the long barrel being more accurate comes from hand holding and open sights. I don't hear many ever mention this, the longer distance between the iron or open sights help in accuracy. Also a longer barrel can help stability (counter balance and swing) in off hand shooting, of course in slower lock time longer barrels can hurt accuracy. IMO this is where some of the lingering longer barrel accuracy mantra stems from.

Thanks guys, you taught us much,,,

brilliant Guys I shoot a maverick and you have you have answered a lot of my questions atb merry Christmas an happy new year

Man I really loved the infoamrion given here! Thanks for that it was a great time just listening to all the answers and it did really help me out as a detail oriented person.

i am trying to find PJ Clark on RU-vid great video. thank you😁!!!

Love your channel btw

thanks guys Merry Christmas to you and your family's

So much good information here. Steve you have been the BIGGEST influence on what gun I select to buy next. I do not have access to see or hold air guns where I live, so everything I buy is ordered online. Back when you reviewed the Gamo Urban I knew it was the first PCP I wanted to have. Now I own two more and one you have not reviewed. The Benjamin Akela. My first bull pup. The detail you provide is what helps me make my decisions. GRAVELY. Which is another reason why my first high quality air gun is going to be the FX Maverick. I want to learn to tune to the T. We are definitely limited to information when it comes to air guns and what you do Steve us greatly appreciated. I really hope there is many many many more years to come. Hopefully until we are old and no longer around. Please don’t stop doing what you do! Oh and thank you PJ for doing this with Steve! I will follow your channel!

Excellent video n content well done to both of you with sticking with this as its a mine field of tuning as said cheers lads for all your efforts on the tech were faced with nowadays 👍👍🤣😅💥💯

awesome vid lovely food for my brain Wayne from South Wales

I love you guys!

Hello Steve and P.J., Just like you guys were talking about, I too have no airgun shops anywhere within a reasonable driving distance. It would take a whole weekend to visit the closest airgun shop, probably in Ohio,as far as I know. That being said...had it not been for you, P.J., Matt, Gerard, Tyler, Travis, Giles and a few others, I would have NEVER trusted that 1500+$ would get a competition level airgun with user friendly adjustability. In 2005 I bought a Walter LG 400 FT air rifle, 6-38X56 walther FT scope, steel scuba tank, and a tin of pellets for $3400. I had been bitten by the airgun bug and I was wanting to compete. The problem was....there wasn't any clubs or competitions within 200 miles. Needles to say, I didn't do much competing, except with my wife. Who ,by the way, could shoot better than I a lot of times. Now,since I bought my Dream tact, I have been bitten by the competition bug again. Guess what?...... Nowhere to shoot except over at Minor Hill where the RAW factory is/was. Anyway... I want to start a club of my own here in Clarksville, TN. I live within 12 miles of a military base and could probably get a bunch of those guys involved. I see a bunch of them at the shooting range just a couple miles from my house. Where would I get the information to find out how to be sanctioned or start a club?? Also, where could I get a list of events and rules for RMAC, EBR, ETC? Any information on resources or advice on how to go about getting set up would be very appreciated. I have had a lifelong dream of competing with like minded people in airgun competition since I got my first Daisy power line when I was 8 years old. If there would have been anything available to me back then, I would have already been competing. That was an awesome ask AEAC with you and P.J., by the way! I hope you didn't hurt your wife's feelings because, I enjoy her comic relief when you guys do the ask AEAC together.

This was good for me being new to PCP still lost though on tuning.

I just can't say anything more but thank you both!

I own a .22 maverick compact. I think that with adjuster maxed (6mm out) and wheel @7, the stock hammer and spring only allows you to go up to around 130 bar before valve lock starts. That’s why they make heavier hammer weights and stronger springs. With that said the way I get to a tune (ie a specific velocity that is air efficient and accurate)is simple. Use the hammer to tune ~3 to ~5% below max velocity. For ex: 915-5% = desired 870 fps. 3% being for longer barrel and 5% for shorter barrel. I first max the spring load ie wheel and adjuster. Then start with regulator setpoint lower than what I suspect will be needed, say around 70 or 80 bar. Adjust up the set point until 915 is reached. Then turn in the adjuster screw and don’t forget to put it back on 7 lol (or whatever number you want to shoot on) until you see the FPS drop to 870. Of course 870 might not be the speed you need for your pellet weight or barrel but that same process is how you get the valve to be shut as the pellet leaves the barrel making it efficient and minimizing air turbulence behind the pellet. Also for one complete revolution on the adjuster spring is approximately 1/2 mm. Which also is the incremental steps on the power wheel.

As I like to tune it, it's 140 bar (all without touching the regulator again) and tune the hammer until it's accurate, moderate sound and not sounding like a crazy goat every time I press the trigger. Only then do I see the speed. I'm lazy and my way of tuning too. For the redesigned, heavy sulgs and .25 caliber.

100 % when I looked at the run time of this video,I thought I can't be assed with watching two guy's waffle on for two and a half hours, how wrong I was, the best video I have ever wanted !!! You guy's have got it so right, thank you so much for putting the time in and putting this together, wow , 👍👍👍👍💜💜💜👍👍👍👍

Definitely not a waste of time, thank you!

😀 thanks for the great content😀 New to air gunning hoping to someday get a pcp.

Yes I just went through that same scenario

👍 More please!

On a quick note right now before I listen to this video...I just want to say I viewed the video you both did at RMAC...you both taught me a ton about gun harmonics...I'm very new to air gunning...I have a .25 cal Seneca Aspen and a LCS SK-19 .30 Cal...I put one of PJ's harmonic tuner and an Emperor moderator... shooting 49 grain Neilson Slugs, reg pressure is at 140 bar, so here I go on trying to fine tune...yes I've seen the temp effect on the SK-19...I would not have even thought of some of the things you talk about tuning...any tips on tuning an LCS SK-19 is appreciated...Thank you both for all you do.

I would like to see American brands show a little more love for the AEAC. For a moment it looks like you're grounded. I would love to see America air arm evol and see RAW again.... Europe and Russia love AEAC for sure. And thanks for your work and dedication to taking sport to a brighter future.

hello AEAC, i find your content about airguns best there is, yet your channel is hard to find you deserve to be front page

Hey, I'm new to the air gun scene was wondering if you have done or would do a video on slugs. Specifically how to know if your gun can shoot (is safe to shoot) slugs, what to look for in a good slug gun, and maybe the differences in tuning to shoot slugs v pellets.

The springers jump not from recoil but from spring tension being released. I find they jump off target before the pellet leaves the barrel. I have a nitro piston and it's pretty bad too. Not to mention the horrific triggers.

What do you guys think about a gun where all the in parts are stainless steel? I understand it would be heavier... but what if you have stainless...brass copper... and cast iron... all at different expansions... throwing all harmonics off? Would 1 alloy stop this? When you work at lower reg pressures... maybe like cast is more porous? Something like that.. just a thought

great video... again. : ) I have a question? when you say when you are shooting in the wind you may have to turn your speed down so the pellet wont corkscrew. So you back off the speed and its shooting great in the wind now. My question is what would the benifits of turning it back up in calm weather just to have to turn it back down when the wind picks up again? Thanks again for all your insight.

Wow guys. Great info here. Watched more than once to glean as much info as I could out of it. A quick question. I have an Impact MKII with the M3 power wheel. Been having trouble with fliers at lower speeds, (880 fps), w slugs and 700 mm barrel in .25. If I’m going to tune for 950 fps w NSA 38.9 gr what’s the PW starting point? Are you trying to get the target at the highest setting or is there an advantage to going for the target at a lower wheel setting? Thanks and keep this kind of thing going.

Hey guys... Wow my 2 favorite air gunners in one show! I'll be saving this one. Been gone a while, just got my "Bullvenger". Haha coming from a break barrel thus feels like cheating. So accurate it aint funny, unfortunately I'm getting a POI shift. Easy enuff to fix but dang it, that's annoying. Probably the scope, it was on a Gamo Magnum b4 but I'm not sure. Any info would be greatly appreciated. And Steve...i do live like an hour from u man, hint hint. Ive got approximately 120-130yds to work with and MAYBE the largest airgun backstop in Fla. Invitation definitely open for Mr.Man PJ. Ive watched tons of his videos as well. Especially the one explaining the flight and BC of pellets compared to slugs. Haha sorry I'm long winded

I guys, Excellent content! Really appreciated! Your suggestion please: 0.177 FX Impact MKII, 500mm barrel Would like to shoot the JSB KO 13.43 slugs. What is your suggestion with regard to reg pressure and final FPS for best accuracy?

Great Job. I've been watching the AEAC channel for year and half now, always learning something new. 1 ? though. Where can I get that cam replacement wheel for my MK2 Impact?

Interesting video. When are you going to do a review for American Air Arms?

These guns tune soooo easy these days. Compared to the days of my Marauder with an internally adjusted regulator, finding balance with an FX is a couple hour adventure at most. It’s squeezing that last 1-2% out of accuracy that will take 99% of your time if you want to compete with the big boys! There’s almost no 100% effective way to verbalize the process. You just have to do it. I’ve shot thousands of slugs out of my 25 Impact and haven’t replaced an o-ring yet. Had the regulator from 90-150bar back to 90 and back to 150. These guns are incredible feats of engineering. One thing I don’t hear guys talking enough about is seating depth. to squeeze the most accuracy out of slugs, it’s an absolute necessity. Get an adjustable probe (pin or pellet) and move your depth forward a few thousanth’s or back a few and then test. When your ES is solid but your groups are not great it’s either projectile length, seating depth or both. Try polishing your barrel, I’ve never gotten worse groups after lightly polishing. I had to polish the heck out of my superior heavy liner and now it shoots beautifully. Clean, polish then clean again. These guys 👆know a thing or three about that! Great hobby, even better community and it wouldn’t be possible without guys like AEAC or PJ. True class acts!

Great video guys!!! I do notice that the majority of tuning videos are geared towards the.22/.25 calibers. I have the Maverick VP .30 cal w/600mm barrel. Would it be safe to say that I could start a tune for a 30 cal using your reg pressures and HS adjustments for a 22/25 cal.? I’m new at this and it’s confusing to me. Thanks !!

WOW Great Video! I have a story about my Maverick Compact .22 cal. to tell you. I want to apologize ahead of time for the long post, but a long video deserves a long post.1 I bought mine on black Friday 2020 with one month wait time. I couldn’t do much testing because I live in the northeast, and its winter. Feb. 10th total knee replacement. March 2021 is here, and testing is on. I have the parts to turn it in to a Slug Sniper 700mm bigger tank. Start testing with NSA 23 gr .217, first problem plenum is taking 15-20 sec. to fill sometimes more. FPS 30-40 avg. differences but not all the time. Plenum stops filling, trip to FX. Get back and O-ring clipped from factory FX fixed. It plugged the hole to fill the plenum I was told. Start testing almost same results but a little better. Not good groups 1 1/2” @ 50 yds, 100 yds 3”-4”. Tuned it the way Steve showed, did not work. Checked liner with bore scope, bad liner and I mean bad. Bought new FX STX Superior liner 700mm. FX did send me a new liner, but I didn’t want to wait for them to send me the replacement. Ok, test again, still not good, go through steps from Steve’s tune process, getting better, but still getting fliers all the time. Average fps 30-40, plenum still taking a long time to fill. After $400.00 plus of NSA slugs and days of testing lost track more than a week. I weighed my options; do I trade it in or sell it with saying that I couldn’t tune it and take the loss and feel like I didn’t know what I was doing? Just to let you know I own a MKII 700mm .25 cal that I tuned, and it shoots 1” MOA@100 yds with JSB 33.95gr and own several more pcps. So, what I did was call Ken Hicks and explain to him what was going on, he said to send it to him, and he would see what he could do. He said he had some special things he can do to tune it. Off it went with everything I had for the Maverick, holding back the kitchen sink. He tuned it to shoot the NSA 31.2gr .217 getting a 1 ½” group with me shooting. The plenum filled in 3 sec. or less. I did not care about AVG, STD DEV, or Spread. But of course, all FX owners know is that you must tweak it just a little more. And what I want everyone to do is listen to Steve and PJ when they say turn the spring screw 1/10 of a turn, they mean it. I turned the screw out just 1/10 of a turn and now it shoots a 7/16” to 1/2” @ 100 yds with that group I had to know the specs, AVG:960fps STD DEV:1.6 Spread:5.0 with 10 shots. My MKII doesn’t come close to this for specs but shoots great. This is all because I sent it to Ken Hicks, I don’t know what he did, but it was the best $200.00 that I have ever spent. Thanks Ken.

When you talk about backing the hammer spring all the way out on a Fx i assume you mean turning it counterclockwise?

Pre load adjustment

How much will you charge to to tune avenger bullpup

Please bring in more “helper” co-hosts

Some guys get excited when a new date is set for a MMA fight and look forward to fight night, I am the same way with your videos Steve!

Plz review aire Venturi bullpop plz ?

When if will AEA, have an upgrade technology similar to that of CAP air guns with the Dragon Claw .50 cal???? I for one will love to see 1100 foot pounds of energy in a AEA Challenger .50 cal...

I would like to know out of the FX guns what is the highest foot-pounds you can get in 25cal top speed with 33gr. I want the highest foot pounds I can get so I can dial down to anything else

Thank you both for taking the time to do this excellent video! Question...when is it time to quit and refill the FX Maverick - 130 bar? They don't mention a minimum pressure in the manuals that I have seen. What do you think?

Hello gents. What is your suggestion with regard to regulator pressure & FPS for best accuracy for a 0.177 FX Impact MKII, 500mm barrel shooting the JSB KO 13.43 slugs at around 100m?
