I have several CZ and they all shoot great. Those are probably the worst groups I’ve seen out of a CZ. Have you tried again maybe after you got used to the gun? Mine all do really well with subsonic ammo. I use RWS subsonic and CCI Subsonics mostly.

Aquila was always hit and miss with whatever I tried it in. It would shoot really tight groups but would throw fliers every 10 rounds or so. Every box, every batch, every gun. I don't know what the issue was but they always did it. They burn dirty too, lots more fouling and unburnt powder. Which is no big deal if they shot well. I want to love them but they just don't have the consistency down.

This thing looks🔥 nice vid bro👌 my only question is what brand light is that on the side? Thanks for the video

Have exact set up for both rifles. I agree with the Shaw on the RPR. The stock barrel is fine. But for the 10/22 I love that Shaw. Also have a Kidd 18” fluted SS that I think is a touch more accurate but idk

You would of impressed me it you were doing this at a 100 yards ...Your right your accessory can very from one manufacturer to another ..

Miss the 22lr content, That being said, If you buy another suppressor, Maybe lean towards a .30 Cal Multi caliber as a dedicated 22lr can. I know, I hear it now… but in my experience, after shooting rental 22lr dedicated cans for years at the range, with only fair results, I finally settled on a Griffin Optimus 9. I only run it on our CZ 457s and B14r. There’s basically no difference in sound, My Optimus comes with a .22 Cal end cap. Dead quiet with Subs, No impact shifts, and for whatever reason, my 16.5” HB 457s with the Optimus shoots SK Match .200-240 groups consistently with the on and off .160s Just a tip. I think the larger baffles help?

Thanks for the videos. Having watched quite a few CZ 457 Varmint + ammo videos on RUclips, I can only conclude that your test results (and with that, your rifle) are an exception to the rule and most probably not indicative of the precision & accuracy of the CZ 457 as a whole.

I know this is a 4 year old video but wanted to chime in. A few guys in our town (very small) started putting rimfire shoots. I thought it would be fun, which it is but I got to watch that I don't go down a rabbit hole with it lol. I have a habit of spiraling out of control with projects. Anyways, I watched a bunch of reviews on 22 rimfires. I didn't have a lot of money to spend so I settled on a Savage Mark II. 275 bucks out the door. 16inch bull barrel. It will shoot sub moa groups all day with SK match and SK Long Range. But sub moa isn't quite good enough. It may do better with some 35 dollar a box ammo but I'm not paying that much. So I came across a Ruger Precision. If I didn't get such a good deal and was easy to get my money back out of it I would of been extremely ticked. It isn't half the gun that the Savage is. Not no where near as accurate and had a lot of issues with failure to feed and eject. So I sold it and ordered the cheapest CZ457 I could find. It's an American suppressor ready with black nylon stock model for $530 It isn't pretty but man it can shoot. It took about 3 boxes of shells for it to start breaking in. By the 4th box it was shooting one hole groups. One group was incredibly small at .285 inches. That's 5 shots at 50 yards. I also shot two flys that were walking around on the target. Best part is that it was the cheaper SK Standard plus ammo. The only issue I've had is failure to fully eject. I gave the bolt a good cleaning and lubricating but haven't had the chance to take it back out to try it. Hopefully that issue will go away. It's also the pencil thin threaded barrel. I figured it would heat up quick and start shooting all over the place but it never really got hot. So I'm hoping I can be a little more competitive since the barrel will drop me down in the standard class from the outlaw class. I can't justify several thousand dollar rifles to enter a competition where you might win 10 bucks a round.

Great video man ! Do you still own this rifle ? Have you tried Norma Tac22 ammo ? Thanks for sharing

I also own a CZ 457 and it is funny to see that my cheap Savage B22 shots better with cci standard. I have to make more tests thanks for the video it is great you are presenting the truth of these rifles.

457 varmint and pro iirc are the only ones with bull barrels the other models have thin barrels

Is 1/2 @50 yards = 1/2 moa or 1 moa? I was under the impression that moa is measured at 100yards?

Damn big boy 7.0 shafts

Got 3 back this week, bought one last Tuesday, one on Wednesday, (Thursday was the 4th and everything was closed), bought one on Friday. Approval emails came back 2 on Tuesday and 1 today (Wednesday afternoon). Get them while you can. I have waited 9 months multiple times previously before this speed up in approvals. No excuses.

So your complaint is about an aftermarket trigger? That has nothing to do with the gun. That’s no psa’s fault bud

Interesting video, thanks for posting it.

Is this at 50 or 100?

BCA isn’t an upgrade. Jk I shot sub moa at 100 with a bca 16” heavy Federal fusion 120 grain

I tried about 25 different types out of my 457. I must admit I was hoping for better also but my results weren't quite so bad. I imagine you sold it by now.

America has never been great.MAGA Make America Germany Again

Didn't notice... but were Armscor 22LR ammo available for testing? Standard, subsonic, or HV?

I know this is an old post now so don't know if anyone has commented on it but the "flyers" you are getting - other than if it was a cold bore shot, is probably due to change of bullet lube. If you go from a parafin wax type to an oil based type you might want a round or three befoe it settles back down.. wish we could get this sort of assortment here in the UK, its abismal here. The gun trade should be ashamed of themselves.

U do fouling shots in between groups? U shot a cloverleaf on that Eley stuff. I bet the lube they put on their boolits coated ur barrel and then the group tightened after. Fouling shots matter

i am REALLY surprised that your cci standard and cci minimags got the same velocity. the standards are supposed to be subsonic but for some reason your box was not.

Great video. I also have that Ruger bolt gun. My only question would be. You keep saying 1.0 and under groups are MOA or sub MOA. If you are shooting at 50 yards, wouldn't MOA and under be .5" and under?

Thats a shame it doesnt like to extract the cci standard velocity. That was by far the most accurate ammo and its very affordable. I was thinking about upgrading my barrel but i dont want to have an exctraction problem. Thanks for the video

I've been looking at this model for years and finally gave in tonight😅 I'll be glass shopping next week.

Leave it fouled then those fouled groups are really good. Try to break it in more😊

May i know the magnification and brand of your scope? I am looking for one now. Thanks!

Where do you buy your target papers?

I did a couple things on mine. Action screws 20 inch lbs. Installed bolt shims .002 to tighten up head space. Installed Yo Dave spring and lowered trigger pull to 1.5 lbs. Do you still have the gun or did you sell it?

Ruger is the most fearless not Accurency is too bad

Awesome I personally love both the lapua and the wolf ammo can consistently hit a golf ball a 150 yards no issue works great

You did not run your ballistics program properly. You have tripled the group sizes. The measurements given are what they would be at 150 yards. The 4.90 you reference on the first target is clearly a 1.5" group. The Lapua Center-X target has two .5" groups that you have at 1.46 and 1.52. It is not just these three groups but those are obvious for anyone to see. Not a CZ "fanboy" and even if you measured them properly they still suck.

you have extrapolated what the group would be at a 100 and put it down as the 50 yard measurement. How else can you fit a 2" group inside of a 1.5" circle. The groups still suck but they are half the size of what you have written down.

me looking at the ammo price and crying

What makes ammo get good groups is the fit to the barrel, imparting the twist by proper fit from the lands and grooves stabilizing the bullet in flight . This is why some ammo seems to work better than others in certain barrels for no reason, it has to do with the fit of a particular ammo . If the bullet is a little loose it doesn't get the right amount of twist to stabilize in flight , this is why a Guy will say " I only run a certain brand and type of ammo in my rifle. Check Each bullet width with a gauge to see what variation are present and which are more accurate in your rifle.

Hope you got it fixed.

Better have order the 150s weaker lofted otherwise you got a gapping problem my man

What distance did he shoot from?

I just bought the RPR. I have not even shot it and have already put the Shaw 20" on it which was the plan from the start. The fit on my barrel is snug but not tight and in fact just like the factory barrel. I did notice that before I installed the barrel I fitted some round into the chamber and the 40 grain bulk ammos were tighter in the barrel to the point that I wouldnt push them in. The 36 grain could not only go all the way in but I could get them out with ease. Im looking forward to shooting it this week. Great video! I do like to watch people shoot but your choice to show the targets was great because of how you had it organized.

Thanks for your candor about your results with this Rifle. This sort of thing can be very frustrating and after spending that level of money I don’t blame you for being angry. I would be too, and as far as I’m concerned you can leave the language in as it helps convey What it’s like to deal with this. You should not have had these problems after investing this amount of money

Thanks for going to so much trouble and expense to test all these different kinds of ammunition and provide an overview of so many results. Kudos. I realize this video is four years old now and from your description it sounds like you have made a number of upgrades since that time. I don’t mean to be critical, although this is a critical comment, referring to the equipment in this video I’m afraid your rifle is just not very accurate. Hopefully with the upgrades you described you found better accuracy with a number of different kinds of ammunition.

I regret buying my American Rimfire. The center line of the magazine does not line up with the center line of the chamber so consequently the ammunition gets hung-up when the nose of the bullets hit the left side of the chamber. Ruger refuses to fix it. Garbage company!

I don’t like the other Federal ammo I’ve tried, however willing to try the white box… looks like a good value too.

CCI blazer is the same as minimag without the copper jacket.

Would like to see if you can get a hold of a Savage Mark II TR ( the one with a 22" heavy barrel ) and see what the difference is. It is a great bench rifle. Here we can not get the ammo you can but using what I can get it seems to shoot tighter groups. at 50yd. and amazing at 30 and 40. where I mostly shoot. Using CCI standard can completely cover a five shot group with a dime, (5/16" center to center) on a good day. And have shot five groups of five all under 1" in one sitting. Would like to see some one who is a better shot, shoot the Mark II and think they can improve on this. At 75 not the eyes I use to be. As soon as the weather warms up, going to try to get out and shoot a lot more, hoping to improve and get all groups close to or under 3/8". Did pick up a better scope but have not even got a chance to sight it in yet. Weather not good lately.

Mount your camera on a tripod!. I could not continue watching your video; I got sea sick watching your erratic video.

Outstanding

Looks like you were shooting a shotgun!
