CZ 457

I had someone reach out to me with a used KRG rail. Guess what I need to install tomorrow?
Brought some 'homemade with magic markers' KYL targets to the range today. That 1/4" dot was dancing all around my shots. Grr
I figure I'll use the timer on the lane and do an ersatz stage next time. Wanted to make sure I could hit the targets period before I made things harder. Till I got down to that 1/4" dot I was doing all right. In a real match, I had the brilliant thought that if you aimed a bit high, the target would still spin...

That 1/4 arm can be a SOB. Of course, that's why they call it Know Your Limits . You can always choose to stop at the 3/4" or 1/2" swinger and save your points. I've been beat several times by those who did when I charged ahead ( beyond my limits)

In the matches I've been shooting it's been hit or miss to move. Not sure how I'd game that. I'd basically have to shoot 2 deliberate misses at that 1/4" and restart on the 1/2" target going back up the line.
Shot one KYL that was hit to move. Got stuck at about 3/4" and couldn't hit the thing to save my life. Shot it after the match was over and had zero problems. Grr

So I've goon from good to quite poor. White target on left was show with my CZ 457 w/ Lilja barrel and Timney trigger in KRG Bravo chassis. SK rifle Match at 50 yrds. Timid wind, 3-4 mph. Orange target is three weeks later with same set up. I suspected a dirty bore and so got to cleaning. Soaked the carbon ring and brushed it with nylon brush. Ran Rimfire Blend through the barrel. Set the action screws to 45 Lbs. Went out was at range at Markham and got the same results as the Orang target(left it in truck) Two Ranger Officers took turns and got same results. Didn't hold for wind, just straight on target. I am at a bit of a loss at what is going on? Cleaned the bolt, though didn't disassemble it. Cleaned all the usual places. Never been dropped or banged around. I am quite frustrated, and honestly don't know what is going on on and how to correct it.
Looking for advice and suggestions, thanks in advance.

Isn't it supposed to be 65 in. Lbs on the action screws and 45 in. Lbs on the tang screw?
There is SO much varied information on the torque value. I was at 65 initial, even split. Dug a around a bit and read 45 was a sweet and correct spot. That's where they're at now. I think I missed the split values recommendation. It would be an easy fix while at the range. I tried 35 and saw no improvement.
regards,
I re-read the instructions, it's 45 for the CZ and the tang (the one that holds the butt stock on) is 45 AFTER the two action screws are tightened.
IMHO, action screw torque won't put your rounds all over the paper like that. Last time I had erratic groups like that, I trouble shot it back the sighting system. Take off everything from the scope rail up and retorque your screws as you reassemble. ( Check the length of your rail mounting screws to assure they aren't bottoming while your at it) If you have another scope, that would be step two.
Good advice from WeeHooker. Action screw torque setting have very little effect on accuracy only vertical shot placement. I would also look at scope and associated parts.
Copied from the FAQ section of the CZ USA website:
Q: “What are the correct torque specs for the 455/457 action screws?”
A: The correct torque specs for wooden stocks is 25 in/lbs, and 35 in/lbs for models like the Varmint Precision Trainer and Chassis.

After taking a good look at this......I would go buy some lots of ammo and retest. I've had a lot of CX that was that bad and I checked everything, switched to Eley Match and it was much better. It just could be that barrel and ammo lot don't mix.
Before I remove the scope, rings and base I will shoot a box of each of these. It's the variety on hand so it will do to get a better idea and hopefully eliminate others. If any of these particular type brings the groups back together, I think it maybe ammo related. I's a slow process as I only have one day a month to take a range trip.

The 457's are amazing shooters. I have three CZ's and 2 of them are 457's. A premium in 22lr and a Lux in 17 HMR. The other is a 452 UL.
You shouldn’t have a problem at all. If anything, you’ll find that the scope sets higher than your cell rest. The Area 419 rail sets pretty high.
thats what I thought you meant just wanted to be sure. thanks mandamn autocorrect! I wrote cheek rest.
Update on my 2 week old MTR.
I was invited to shoot a 50y fun match last Saturday.
I’ve never shot a Benchrest match before let alone a rimfire Benchrest
There are 2 classes -10.5 lb and +10.5 lb
That’s rifle with everything on it except a magazine.
My MTR weighed in at 9 lbs 15.5oz bipod included.
Myself and 2 others shooting Savages were in the -10.5 lb class.
In the +10.5 there were 9 Annie’s and 2 RimX
We were 14 shooters in all.
I finished in 7th overall winning the -10.5 lb category. I finished ahead of 3 Annie’s and both RimX.

Just keep looking and maybe you’ll get lucky. I’m pretty sure I saw someone selling one in the PX here just in the past month or so.
I’m going to put my 457 in a chassis. But is it worth spending the money for a chassis like the ACC or should I look at something else.
Will be shooting NRL22/X
I like the looks of the acc but would love to find a used beat up one. Might make the wife a little happier.
Thanks.

I've got a CZ 457 Varmint Precision Trainer MTR that I picked up in the spring that I haven't purchased a scope for yet. I know that there is a optics forum, but since this gun series has such a following, I thought it better to post in this thread. I'm looking for recommendations or guidance on scope and mount. Right now this is just a range toy, but I could see getting into matches once I have more time in a few years.
Not looking for budget options, but also not looking for a 5k Nightforce offering. After some research, my initial inclination was to look at the Burris XTR III illuminated or Pro series. Even if I decided on one of those, they're each offered in at least three different reticles, which is probably where I need the most help. So I'm asking the hive for recommendations on scope, reticle, and mount. Links to recommended sites to purchase wouldn't hurt either.
Thanks!

That’s such a loaded question. In reality, reticles are a a personal interface to your rifle like the ergonomics and trigger feel. What works perfect for an individual may be awful for another.I've got a CZ 457 Varmint Precision Trainer MTR that I picked up in the spring that I haven't purchased a scope for yet.

Go to a Scheel’s, gun show, or similar where you can hands on look through scopes and get a feel for which you prefer. I would only suggest 5-25x and MRAD. Mostly you’ll be at 12-15 maybe even 18x.
I’m trying to go common reticle on my scopes but can’t afford it in every rifle I own.
Hey friends, I just installed my cz457 in a MDT ACC chassis and i have the anarchy outdoors extended mag release. However it is not near long enough. Are there any other options to make the mag release lever easier to get to?
thanks
thanks
I think DIP or area 419 make an extended release too. I know one of the 3 is supposed to be longer.
I bought the DIP extended release and they were only about 1/8" longer but it makes a big difference in finding it.
I ended up with removing all the optics kit, base rings and set aside the scope. Checked each piece and set it all back. Bore sighted as before and headed to range. Wing was pushing 5 mph with a frequents gusts that took some targets off the posts.
Shot SK rifle match and it took about 15 shots to zero at 25 yrs. Had to dial the scoped past the point I believe it should have needed to go and then come back to the zero. Think of it as a worn out hotel shower handle. You have to go past the perfect temp. and come back to it.
Set out at 50 yrs and this is the best I was able to get. Wind was a factor, though not sure how much.
Contacted Vortex and they agreed to check out the scope. It's a Venom and has shot quite well before, as did the entire setup. If it is the scope, I know they will fix it.
ps, left the selection of ammo to test at home, that's why I shot only the SK rifle match.

DIP is very short. Anarchy Outdoors has 2 different models. One with the paddle (now aluminum) and one without. the one with the paddle is the longest I've seen for these. non of the others are as long. I though MDT has a magwell insert, maybe ask them if they have an extended mag release for use in their chassis.
I'm very happy with my CZ 457 Pro Varmint. First time I actually measured groups(normally just plinking). Ammo is Wolf Match, but also had the same stamp as SK I was also using. I didn't measure the SK groups because it was me just drilling 20rds into a single target fairly quickly.
Only thing added is Harris bipod, Bradley cheek rest, Area 419 50MOA rail/ARC rings/Athlon Midas TAC. 50yd zero.
100yds indoor shooting kind of fast. Any other ammo suggestions?

First off, All Wolf, SK, and Eley, along with others have that same head stamp, so that means nothing other than who manufactures it.
Which SK were you using and have you tried shooting a group with it? Have you considered slowing down just a bit and making sure that each shot has the same POA and trigger pull? Just flinging them down in a hurry is fun, but rarely tells you anything about what results you can expect to achieve for accuracy and repeatability.
The SK Rifle Match is a decent mid grade ammo, but then you’ll need to step up to higher grades if you feel you need an improvement. Like Center X and the like. Then you’ll find that there are variations in lot numbers of the same ammo type.
ETA: also 1” at 100 yards for ten shots is not bad at all for .22LR.

just got my 457 in the Boyd's AT-one
dropping ring height tomorrow, but may still need a little more cheek-weld elevation help
has anyone used either :
1) the very nice looking Velcro one from wield? and if so which one, (since they don't make on exactly for this stop?
how'd it fit? picture?
or
2) the adhesive one from hoptic? and again, which one? or just the generic one and trim to fit?
anyone ever try to remove an adhesive one/ are we talking permanent residue???

If your going to run the cheek riser ( or butt pad) out near it's limits, you'll find that the adjustment gets wobbly. You're going to want to stack some hard rubber 0-rings on the rods to stabilize them. As for adding a pad, I've been using the anarchy outdoors brand on my Bergara and CZ's. Quality is good but they are only 1/8" thick. Last I looked, they had a cut your own generic option.
I have not installed the O ring fix for my own At-One as I'm not a tall guy so didn't need to extend the adjustments but a little. My cheek and butt extensions are as solid as a rock. I mentioned this because slop in the At-One extensions is a common gripe among owners that set them way out. As said, it's only really "needed" if you need allot of extension and have wobble in those pieces. I do know several others that use this method on the AT-ONE on another site though. You'll want both 1/4" ID and 3/8" ID O-rings to fit the rods on the AT One. ( OD and thickness aren't real important but bigger is better.) These are available all over Ebay and /or Amazon pretty cheap. Get a bag of 50 min. You basically just stack them on until you set the proper height.
FWIW, here is a picture of the O-ring set-up on my Bergara B14R. I use it there primarily because the cheek piece needs to come out every time I pull the bolt. The O-rings, besides adding extra stability, bring the cheek riser height back to the same height every time . Works VERY well and is completely adjustable/reversible.

Hi Guys
I keep seeing reference to 2 action screws and a tang screw?
My 457 only has 2 screws, it's a LRP.
Are there different 457 actions?
The manual only shows 2?

Are those references to 3 screws made specifically regarding the 457, because there are only two screws on that action. Now, people with vudu or Rim-x will have the three screws as in any centerfire short action.
All 457 actions are identical regardless of model. All use only two action screws. If there are three screws, it's not a 457. Earlier model CZ rimfires ( i.e 452, 453 and 455) did have a 3rd (wood) screw holding down one end of the trigger guard but it was not an action screw..
