Breathing techniques all use are useless in the real world No grizzly bears wait for you to take your breath You’re dead meat 😂 Try my method Inhale and expand rib cage to maximum and lock it then switch to shallow breathing by diaphragms You will never run out of air and still maintaining rock solid hold This technique will work for any shooting Try it you’ll like it
Great informative video. I was always taught to take the shot only during the natural respiratory pause, so you just gave me another option. Quick side question: I have the same Swatcom Active8 muffs (same color too) and was wondering what that item attached to the left muff is? Is this to hook on a belt clip when not in use? Thank you.
Thanks for watching and posting. The clip you see on the left side is for comms wire. I have these set up so I can hear radio transmissions through my Swatcoms.
Very professional. You do yr homework! Americans, from my experience, r good people. U slice and dice this information like a recipe. I simply enjoy the physics and kinetics.
Thank you James. I am glad you enjoyed our video and welcome to our channel. We have viewers from various other countries (Australia, Canada, and Ukraine). If you don't mind, what country are you watching from?
Great job as always, cant believe i didnt subscribe earlier. THANK YOU SO MUCH FOR SAVING ME THE TIME AND MONEY DOING THESE EXPERIMENTS . Shooting only 223/556, an hour from home, 100/200 yards maybe four times a year, at least for now i will only separate by headstamp, and concentrate on other variables again. Thanks to your work, I will enjoy reloading more with my 223/556, I'll assume the same. After that... another cartridge!
Thank you very much Bruce. We are doing our season of PAC-T tests right now and just finished testing Liberty Ammo's Civil Defense 50 gr. bullet in 9mm. Here is the link if you are interested ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-aU6-OIlkKJ0.htmlsi=zZOq00bwFhKvucGS Thanks for watching and posting.
Great test and happy independence day! Gotta say I disagree though. I think this is one of the more effective rounds on the market today. For what it's worth, I read about a guy who used this round in a self defense shooting protecting himself and his girlfriend at the time. The perp was shot once in the chest and dropped where he stood. Only shooting I know of so nothing conclusive but worth mentioning. It's unfortunate you couldn't get reliable readings on the ammo. The velocity is usually well above advertised. Thanks again for the test and take care.
Thanks. Nothing wrong with disagreeing as there is no absolutely definitive answer to my tests or anyone else's tests. They are tests and not reality. In fact, even a bullet that works once in reality may be shown to fail in another instance. Here's the key: this fellow did it just right: A well placed shot... that is the key to making any bullet perform. Thanks for sharing that!
@@sdkweber well said! That's very nice to hear. Alot of guntubers test a round one time and draw conclusions from that. Can't wait for your next PAC-T test!
Yes, probably a few better choices out there, many of which you've already shown us. These might do better from a 9mm carbine or something similar, but as you said, shot placement is key. Anyway, happy Independence Day good sir! A great video for a great day!
@@guardianminifarm8005 Very cool indeed. Do tell about what you learned from 16 vs. 26" barrel .308. Did you really see a tremendous drop in velocity in the 16" rifle?
@@sdkweber I have recently tested about a dozen handloads all at near max with the best powders for the caliber using 150, 165/168 & 180 grain boat tail bullets(SST, NBT, MatchHP, BTSP). I have also tested a couple factory loads(Superformance & Win Power Point). The range has been 185fps to 330 fps. Most are landing 200-250fps difference.
@@guardianminifarm8005 That is interesting. I have read each inch of barrel gives you about 25 fps difference in velocity and your test pretty well confirms that. A 10" difference in barrel length giving you 200-250 fps difference in MV. Thanks for taking the time to post that and answer my question.
Enjoyed the video. A few suggestions: 1. Buy a Garmin Xero 2. If you’re going to use the LR buy a magnetic trigger.3. Also, it helps to set the lab radar at a slight angle towards the path of the bullet . This gives better readings because the bullet will spend more time in the radar.
Thanks. I never had such problems getting muzzle velocity before and I think your suggestions for the Labradar are good. I will look into the magnetic trigger for it. Any suggestions by the way?
That bullet penetration was more then 8in, it went to the end of that bullet track and bounced back,, it would have been right in the penetration your test likes that 11 to 13 inch mark,
That is too bad. Sorry to hear that. I have not tried Corbon DPX in my .45s, just the 9mm (and I think it is great in the 9mm). Another great round is the Federal HST, they make a 230 gr for 45 ACP and it shoot flawlessly in my HK 45T.
@@sdkweber okay thank you. I'm just a fan of the 45-70 and I'm looking for some in depth videos on reloading for it. Do you have any on loading for the 30-30?
@@jmc041071 I have not done any videos on reloading for the .30-30, but it is really no different than reloading for any other rifle caliber. I guess, the only difference would be to take great care when working up the load to ensure the rifle (in my case a lever action Winchester) functions perfectly with that load.
@@sdkweber I figured the process would be the same I just like watching videos of reloading. I love lever guns but unfortunately don't have one yet. Hopefully soon. And I'm very Interested in reloading. But when I start, it will have to be with the basics at first.
Why do you compare a regular load with a +P load and not make that clear. Waste of time video..... +P federal HST won in a gelatin test. Because its a higher pressure. What are you doing and why are you wasting our time.
Not really. We are testing various factory ammo in it normal packaging. I have tested a lot of ammo and the performance difference between standard and +P is minimal.
You are welcome. Yes, the ARD killflash does work and we have another video on the same topic coming out regarding scope detection at night. Thanks for watching.
I have a question about bullet weight. I use 69 grain Sierra Match king bullets. I weight them and I have from 69 grain to 69.4 grain bullets. To get 69 grains does it effect the bullet to sand off the excess off at the base of the round?
You will find some variability in the actual weight of most bullets. You can sort them by weight so as you shoot them each group will be consistent. Do not try to alter the bullet because doing so will effect the aerodynamics and flight characteristics of the bullet even if you work on the base of the bullet. That is the place where the air currents meet after passing over the bullet and form some turbulence. Altering the base of the bullet will alter the airflow dynamics as is not recommended. I hope this helps.
Another great test! Glad to see you have Civil Defense. I really like how you give results on recoil compared to a target round and i like the closeups on the wound channel as well. Great additions! Itd be great to see a PAC-T test on Simx Defensecore as well.
Thanks much. I just took at look at Simx Defensecore online. Interesting stuff. I see they have some new bullets coming out also with a ceramic core. Very interesting and thanks for the idea.
Thanks for changing your process. I never liked how you scored a bullet score even though It was not sighted in. It would be interesting to see how some of the other bullets would score based on the new process. Thanks for another fun video
G9 is barrier blind ammunition that maintains its POA/POI while penetrating difficult real world barriers such as windshields and bone. This capability opens up a range of possibilities including being able to penetrate the skull outside of the traditional ocular cavity. While your PAC-T methodology may be fine with hollow point technology, your results would be much more comprehensive and meaningful if you expanded your PAC-T protocol to include challenging barriers that are faced in the real world and applied this standard to all types of ammo. Doing so would position G9 in the broader context. I mean, who cares if brand XYZ has better penetration or temporary wound cavitation in your test if the bullet is stopped or deviated by a barrier?
Interesting note. I think the test we did with a jacket and leather barrier emulates a real world situation quite well. Realistically, most of us are not going to be shooting bad guys through car doors or glass windshields but much more likely confronting a bad guy at close range with nothing between us but clothing. Do you see what I mean?
@@sdkweber If we are talking about an ATM robbery or carjacking or even home invasion, perhaps you are right (although I live in South Florida where most people don't wear leather or jackets). I am thinking more of active shooters, body armor, store robberies, gas station encounters . . . situations where you may have barriers between you and the center of mass that need to be breached or adjust the firing solution for head shots. Regardless, I think not taking into account one of the key benefits and purposes of barrier-blind ammo like this, and then comparing it to conventional HP technology is shortchanging the viewer both in terms of analyzing the results as well as considering self defense scenarios.
@@karimmanassa9634 Those are indeed more extreme scenarios, still I wonder if most people will ever be in such situations. As a civilian would it be best to just leave the area (if possible) instead of trying to shoot? There are a myriad of variables and trying to cover each would take a lifetime. BTW, One of my favorites (favorite only because it did so well in my testsl) is the Corbon DPX. A very good barrier blind bullet in all tests thus far. We have videos these bullets also. You got me thinking about some additional tests now. Thanks.
Fluted solid monolithic bullets are designed to produce exceptional wound channels and I do not think the G9 performed that poorly. However, its penetration was totally unacceptable. I have seen tests of the Underwood 90gr Xtreme Defender, with a similar fluted monolithic bullet (made by Lehigh), perform much better overall.
Thanks for watching. I have tested the Underwood ammo 105 gr. but not the 90 gr. Here is a link to that bullet's test if you are interested ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WWcX4W46ryw.htmlsi=RWFBV8seMdss1ZfO
Now we know what happened to your old Carhartt! I really like the changes and additions you're making to the PAC-T test and you've certainly selected a great group of bullets. It's easy to almost want to give the HST and the Critical Duty/Defense loads a pass because of their reputation but your testing will certainly make a difference in future buying decisions. I think where the G9 and similar bullets like the Lehigh Defense XP would shine is in a one for one exchange over standard ball ammo when trying to penetrate heavy winter clothing like down parkas or, God forbid you had nothing else, thick skinned animals like a bear. I'm curious, do you watch the RU-vid channel The Ballistic Machinist? He manufactures and sells his own ammunition and the results from the 9mm are compelling. If you have a few bucks left in your pocket and think his tests merit the higher standards of the PAC-T, it may be worth trying a box. Cheers!
Hey Aaron. Yep, waste not want not! I figured I may as well put my old jacket to good use plus I think it makes for a more interesting/realistic test. I have not watched the Ballistic Machinist but will check it out later today. Thanks for the note.
@@deenyc1049 I understand and that sounds like an interesting test. The pistol I used in this test has a 4.09" barrel. I do not have another with a 3" barrel. I will see if someone I know around here has a 3" bbl. 9mm pistol I could use for the test.
So much packed into this video. It is almost maddening to imagine how much manual calculating post Civil War snipers must have been trying to do with a little pencil and scratch pad to record their dope. It's certainly reasonable in today's world to send a sniper team to gather data in different climates without much fuss. I'd guess that anything pre-1990's though must have involved a lot of on the fly guesswork when guys were dropped into a strange environment with a target list and expected to score the hit.
The hand calculations and inherent errors of poorly fit models (older BC) would have made me call it quits. That's probably why "Kentucky windage" became so popular.... and with an experienced shooter, it also became effective. Thanks for watching and posting Aaron.
Don't forget that the speed of sound changes with environmental conditions. 4dof uses mach curves not bc. As your speed changes your efficiency of your bullet changes
Correct. And that is an advantage of both Hornady 4DOF and Lapua 6DOF. At the same time, the effect of these variables are slight. Thanks for watching.
The disintegration part is BS for sure. As someone who comes from a lot of high power PCP experience i can assure you that there is no such thing as the trans-sonic tumble or yaw which ppl claim. Airguns also have the advantage of very little velocity spread and SD when regulated and this has been proven wrong many times over.
Dang, there accualy is a scope mounted , missed it somehow. Lol. May be a little , little but it's a S & B . I've heard good stuff about that system also. Ronnie and son design , build and maintain their rifles primarily for the military. They understand the importance of accuracy and dependability. That's just awesome in my book. Thanks for sharing.
