CZ 457 VARMINT MTR .22LR with SK LONG RANGE MATCH @ 50 yards 

That CZ is flat out a tack driving machine!

This is such a cool series!

So far with all the different ammo you have shot, I am impressed with that rifle . For an out of box, You shoot it very well.

Keep doing what you're doing how you're doing it! Thanks

Your doing an out standing job.

Excellent information regarding the supersonic transition. Keep up the great work.

I really like your consistency in testing. Thanks for the video.

Deviation in flight from supersonic to subsonic will cause vibration, flight disturbance, but by the groups, it certainly is not significant. I had a close Boeing friend, MIT man, who spent many hours in wind tunnel tests. I'd think, molecular compression, constriction due to temperature would be more of a factor in velocity, but, you'd have to re-run the same tests during higher ambient temperatures like summer, using the same ammo to compare velocities. Just same, keeping it simple, I've YET to be NOT impressed with that CZ! The guy behind the trigger isn't bad either! Both super performers! I came here for Beowulf, now I'm here for whatever is served up. Great job on every video!

This is a GREAT Series!! Thanks so much. Picking up this model hopefully by weeks end & your series is perfect. Thanks Again.

Lovin' the sound track at the start. LOL Nice video.

Thank you.

I’m such a big fan of CZ.

That was good shooting again,...I do enjoy these 'ammo. tests'.

Love your videos and techniques. Keep up the good work. You're a natural in front of the camera.

Great video Buffalo !

Wolf Match! Yes! It Is Manufactured By Eley. A Hidden Gem Of .22 Ammo.

Great stuff as always buffalo thanks for bringing us along.

I have lots to choose from but it's the price tag I look at before anything!...enjoy your videos Buff.

Excellent. That discussion about going trans sonic was great.

love the chicken pickin in the background!!

The more I see you shoot that rifle, the more I like it.

I watch a lot of Gun RU-vids and I have to say you sir, are certainly one of my favorites You and Mixup 98 are great.

Great videos, I love this gun. Love seeing the comparisons on the premium ammo I am also testing!

Mighty fine shooting their buffalo. Great video as always thank you for what you do brother

Great work Buffalo. I like your tests and not least your music. Got a CZ Thumbhole and SK Standard+ does a very good job. Greetings from Germany, Mainz Area.

Being a banjo player I liked the music at the start of your video. I also shoot a CZ 457 mtr I have a Harrell's tuner on it And it works great. Thanks for the great videos keep up the good work.

Not even watched the vid yet Buffalo and i already know it is safe to say.(you are absolutely correct and splendid behavior)keep your powder dry and your mind on JESUS

You Sir, make very nice videos...............................Thank you!!!

Best ammo series on RU-vid! Have you ever thought about doing .22 re-sizing thru a die? Just to make them more accurate?

Thank you very much. This is very interesting. And shooting a bolt action .22LR rifle is very enjoyable.

Love these - keep up the great work

Really great point about bullet speed. You are correct about the supersonic to subsonic transition. Very much an issue even for fighter aircraft. Ask the very long range comp shooters and they will tell you how much impact it can have. I.E a lot!

Nice groups!! That brick of SK sure did look pretty 😉 Thanks Buffalo!

How are you doing my friend I love your post I have a CZ in my collection you have a wonderful day

This series is excellent

Great video! Like your attention to detail. I lost the moment where you said what distance you are shooting, trouble finding it back.

Outstanding shooting friend. May your channel blowup into millions of subscribers. Great presentation and showmanship too! 👏👏👏🤝🤝🤝

lovely rifle

Buffalo If it becomes available I would like to see you review Cci standard velocity and Cci green tag even if it after this testing.

I like your methodology, great series!

Howdy Tatonka!

hello, nice video, but you definitely need an old Brno model 4 Aeron single roundg follower, It can be inserted as your magazine and it allows you to load the gun one by one ...

Well.....another fine video Buffalo. Thank ye.

Very consistent velocity..great job..

That's some wicked consistent ammo!

The stock on that rifle awesome looking.

Nice video Buffalo

My new 457 Pro Varmint is in the mail on the way to my local gun shop:) Can't wait to go pick it up. If they threaded the barrel, I would have bought the one that you bought.

Another great day at the range. I seen some SK ammo 6 months ago and didn't get any. I missed the boat on that one it seems to be good ammo. But the CZ is performing perfectly. I like thier rifles better than thier handguns.

Good to see you using SKLR Match ammo. both my CZ457s love this stuff. I have the MTR & Varmint nothing in it for accuracy. 2x10 shot groups 9.6mm. I do weigh & measure length though. Length varies by 0.011" causing velocity variations/re P.O.I. change. Also have found SK Std Plus shoots tighter groups in both guns.Also sorted by length. Ray o.

That’s very impressive

Buffalo thats a good lookn rifle , great video and excellent shooting as always .

Nice shooting you are doing a fair testing don’t change it , it will be interesting to see the three best when it get here. Stay safe 👍

Hey Buffalo! Great series. So great I went out and picked up my own 457 Varmint and it is a tack driver. You mentioned trying Wolf Match Extra. My 457 absolutely loves that ammo. Anxious to see your in depth testing on the Wolf ammo.

I have the Browning t-bolt target/varmint with a Leopold VX Freedom 2x7x33 and I shoot the SK Standard Plus in it and it loves it. @50 yards I shoot the bullseye and then I put the next 9 bullets in the same hole. This setup is the most accurate I've ever seen or had. I'm going to try it with the Long Range and see what it does.

I saw the surge on ammo coming so I bought 1000 CCI green tag and 1000 CCI standard velocity. So far my MTR didn’t care for either of them. After about 15 different brands and types, RWS Target Rifle and another type of RWS have consistently shot the best. Since premium ammo is hard to find I’m saving your results to help, if and when ammo becomes available. Thanks again. Ps. Best bumper music on the TUBE.

I ain't believing the consistency in the coronagraph reading of those rnds !

Good vid & nice shootin👍!

That stock is UUUUUGLY! Nice rifle, though!

My suggestion is for Buffalo to do Buffalo,,Most of their suggestions will contradict each other,You do a DANG good job!!

I really enjoy this CZ 457 "series" of videos as they are both informative and therapeutic. Ever notice Buffalo's up votes to down votes ratio? Says a lot.

Is there a reason you don’t shoot out of the magazine? Love the vids, just confused as to why you break your hold every time to load the gun when it has a magazine.

I’ve always been impressed with your videos and ability to shoot well.I’d like to know as to why you do so much thumb adjusting. Might it be done for leveling the firearm?

Love your work.

I believe with that rifle you can shoot just about any ammo and get decent groups. They have all looked good to me. Nice shooting!!

just bought some SK match and SK standard plus to test on my new rifle, looking forward to it. Wanting to try SK long range as well

I'd like to see you try maintain a constant cheek weld and load from the magazine for a full string. . . Very watchable . . .niceee

I don't have any CCI standard velocity, but I have a lot of CCI 40gr mini mags if want to test it

Another great video. Dang, I need to find some of this brand and see how it will perform in my old tbolt

Love this series! The use of the chronograph really shows the variance in velocity especially when you shot the Federal bulk, 48 fps difference from the fastest to the slowest. Most the SK's is maybe 20 fps. I have found my CZ457 Varmint MTR likes all the SK brands, but loves the SK Pistol Special. I was wondering if you would consider sorting by weight & rim thickness when you get down to your top Three competition? Keep up the good work!

That CZ shoots almost as good as my Marlin 39A Mountie did in 1965. OK I guess my memory might be embellishing that a little bit. Give me a couple more years and that Marlin will be shooting 1 hole groups at 100 yds. All joking aside that CZ is a nice rifle and I like your testing technique.

The designation of the ammunition as long range might suggest it design was for it to have the least effect on accuracy at a specific range. It might be; it will shoot more consistent groups at longer distances than others traveling slower than the speed of sound. I have had better luck using 1200 feet per-second velocity loads at 100 yards I believe for the same reason. By the looks of your velocity results; this brand might have a lower velocity deviation than others you tested. It is common the ammo that groups best at 50-yards may not be the brand that groups best at 100-yards. It is true that shorter barrels produce higher or equal velocities as longer ones. However; longer barrels provide more spin to the bullets than short barrels. The bullet rotates one revolution in 16 inches; in a 24-inch barrel it rotates 1½ times before it exits the barrel. What you choose to believe is up to what shoots best for you. I have both and on any given day one might shoot better than the other.

Thanks for this nice video. I really like them! I have a question (but maybe you already mentioned that in one of your videos) Why do you load your shots manually, and don't use your magasine? Just so you are certain that there is no deformation of the bullet from loading from the magasine?

Why are you not using the 5 round magazine? Noticed when the velocity dropped down so did the shots.

I haven't seen you try Federal yet. I shot BR 50/50 years back and that's the ammo all of us used. Premium match ....try it.

SK works well. Good stuff. Try SK Rifle Match if you can get ahold of some. Its round nose like the Long Range and Standard Plus.

Nice shootin Buffalo 🐃. Its to bad your closer to me. I have some cci that id let ya have for the shoot 🔫 cause I'm definitely into this. Sorry but the pictures 📷 😅

Can't complain about those groups! I haven't got a chance to take my MTR out yet but I picked up all the different ammo you have tested plus some Lapua X-Act, when I do get out it's going to be a long day of bench shooting.

Its not the worst problem in the world to have, being "stuck" with such good ammo. =)

This is very interesting testing Buffalo, but it leads me to a question. Is the CZ match chamber cut more conducive to Lapua/SK ammunition than Eley? SK and Lapua really owned by the same company and now made in the same factory (Nammo Group of companies and made in Schönebeck Germany) Wolf the new stuff is now made by Eley. SK is aimed at the middle tier and Lapua at the higher end. SOOOO with this information, if the channel came together to get you some high end Lapua I think we would want to see that tested? Like Lapua Xact or Lapua Midas+ 😂 ain't it great when your friends push you further down the rabbit hole 😂

great series, why don't you use the magazine

I wouldn't change a thing on your Rifle or your setup that is shooter for sure.

That is a nice, accurate .22. If I were in the market for a .22 target rifle id consider it. Right now, I'm just trying to find .308 to feed my new Savage 110 tactical. And 5.56.

Good looking rifle, I’ve not seen that particular stock

I need one of those.....bad.

Hey Buffalo, nice shooting as usual. You mentioned that you may fidle with the set up at the final three. Maybe best just to do everything the same as when you started.

Believe it or not, the Wolf Match is crazy accurate out of that rifle.

Another great video mr. Buffalo! I got a 44 mag that I'm shooting out at a hundred yards and I'm just wondering because some bullets I can't get them to group very well and if that is the reason why, the bullets are going from supersonic to subsonic

Glad to see another ammo test. Stick to your guns (no pun intended) on the test method. Like you said you have to keep it consistent.

21 FPS spread not bad at all. I would love to see agulia extra and cci standard threw in the mix. If you have a few laying around. Hell auto match as well, while I’m making list of stuff up.

I like the flag on your bench. How did you apply it? If I missed a video on it I apologize.

You ever try shifting your point of impact, maybe one click off the center of the target? The benefit would be the center of that target doesn't change, bullet impacts don't chew it up. Depending on my reticle, I can still "bracket" between 1/2 mil marks, or just use a crosshair to stay centered, so I don't always do that. Good shooting as usual.

100 yard test please

@Buffalo's Outdoors ... do you folks have a rumble channel, or possibly a full30 channel? I'm on both and looking to rebuild my uootoob subscriptions so I can get off uootoob. God Bless and be well, from Alaska.

Buffalo. Try armscor 40g lead round nose, standard velocity. It’s a great performer and inexpensive.

Buffalo, is that you on the banjo? Thanks for the info on the temp and speed of sound at the end. I never knew that was a consideration but it makes total sense.

SK is good stuff. Standard Plus is nearly as good as CenterX and Tenex and a third the cost.

I think you are doing a great job. You have probably improved and got used to this rifle as it has bedded in so I think you need to shoot the Midas and Tenex again as I suspect you would see a better result with them.

Buff......I get what you're doing. BUT.....As a Precision Rifle Enthusiast for a while, I feel bad for commenting. There are sooooo many variables to consider. My first concern is your "clean cold bore" shot. or even "fouled cold bore" shot. Alot of things change as each round is sent down range. consistency WILL change from the first shot to the 20th shot. It all depends what your barrel likes. from what im seeing.........your barrel seems to do goon on most ammo.......but as it warms up a bit (or fouled out) it seems to vary some. So.......if its a squirel hunter......it does great from the first 5 shots. Then the barrels warms up.....or....its fouled out and doesnt like it. If its going to be a MOA range toy........We have to figure out if its the heat or the fouling it doesnt like. My rifles....have a different clean cold bore shot compared to a dirty cold bore shot. And as the barrel warms up.....they all usually end up in the same place. Most of the time, barrels prefer a dirty bore and get the best consinsty that way. This is a tail chasing game that will get ya going!!!!!! Oh crap.......Im about to get called to the carpet by the Buff!!!!!! Love ya!!!! Stay safe!!

Dang Buff, I think you can out shoot me with your eyes closed!! Good shootin Bud!
