Giving up on my CZ 452 - Find me a good .22WMR rifle.

Discussion in 'Rimfire Forum' started by Mercedesrover, Jan 11, 2010.


  1. I've had my CZ 452 American for almost a year now and I just can't seem to dial it in. I've floated the barrel and installed a Brooks kit. Didn't seem to help much. Out of a 5-round mag at 50-yards I'm getting 3 maybe within 2", maybe, and two fliers off into the wild blue yonder. I've tried a dozen different brands of ammo, warm barrel, cold barrel....nothing seems to help.

    Just yesterday I had it out on the range for another try and also brought along a 9422m that I just bought to sight a scope in on it. This old lever gun was shooting circles around this CZ. I mounted an old Bushnell 4x scope on it and was drilling 1" groups at 50 yards. So much for the CZ...

    Anyway, I want to find a bolt-gun that will do sub-1" at 50 yards and 2" at 100 yards. I don't think I'm asking too much, though I know that .22wmr isn't the most accurate round in the world. I don't really want a varmint barrel as it won't get shot a lot, though if ya'll think that makes a huge difference in accuracy, I'm open to it.

    So I'm looking at the Savage 93 Classic. It's a pretty thing and I like the 24" barrel. Any other thoughts or suggestions?

  2. The Sako quad's in WMR have a very good reputation. Last year I got a bug for a accurate WMR and after spending a lot of time on rim fire central I decided to buyt a quad, since then I have mounted a scope on it and have yet to sight it in. So much for the bug. LOL
    It is a nice gun and it has a adjustable trigger.
     

  3. Don't give up on that CZ. It's an excellent gun, and should shoot well.

    Obvious questions first:

    1) Is the barrel clean or full of lead and old wax lube? Inspect with a bore scope if you know someone who has one.

    2) The fliers you describe sound like they could be caused by a damaged muzzle crown. CZs usually have good crowns, but there can be exceptions.

    Inspect the crown visually, and if there is any doubt about it, have it re-cut. (Be careful of the crown when cleaning -- most crown damage is done during cleaning....)

    If the barrel is clean and the crown is properly cut and undamaged, try these steps in order:

    1) Bed the action with some AcraGlass Gel where the screws pull it into the stock.

    2) If it does not shoot well with the action properly bedded and the barrel fully floated, bed the first couple of inches of the barrel.

    3) If still no joy, try some cardboard pressure points against the barrel just back of the tip of the fore end. If that gives good accuracy, replace the cardboard with little columns of AcraGlass Gel.

    Somewhere in that process you should get good accuracy.

    sell it and buy a .17HMR
     
  5. Lemons happen in every manufacturing environment... :whistling:
     
  6. That's true, but unless the barrel itself is fundamentally bad -- which seems unlikely with a CZ -- any problems with the action bedding or the muzzle crown can likely be found and fixed.

    Until those possible causes have been systematically investigated and ruled out, it is too early to give up on the whole rifle.

  7. By the way, another area to investigate is the rifle's scope and its mountings, even if all seems tight.

    I've cured mystery accuracy problems in people's rifles by replacing the scope base, rings, and scope -- even when there was nothing apparently wrong with the existing setup.

    Scopes go bad all the time, and play can exist in bases and rings even when the screws are tight.

  8. Thanks all. Although I floated this barrel when the rifle was new, I pulled the stock and gave it a bit more clearance. I really don't think it was touching but a little extra room can't hurt.

    The barrel is clean and the crown looks fine (to the naked eye).

    The scope is mounted with a Rimfire Technology base and Weaver Quad Lock rings. The scope is a Nikon Monarch 6-24x50 and I've always had good luck with Nikon scopes.

    I'll try bedding the action and give this thing one more go. Unfortunately I won't be able to get back out and shoot this girl for a couple of weeks now, but I'll report back when I do.

    If that doesn't help, it's going back to CZ. I've already gotten in touch with them and they seem great and willing to help any way they can.

    Thanks for your help and suggestions. I'll let you know how I make out!

    Both my Ruger stainless bolt action and my Marlin 922M 22 magnums shoot very well with Winchester ammo, with others just so-so. Winchestes has a real copper jacketed bullet, most other makes just a copper plated bullet. Try the 34 grain SXT's or 40 grain hollow points.
     
  10. Well, I floated this barrel and made sure there was plenty of clearance all around. I took this CZ to the range today along with a 1974-built Winchester 9422M to have another go at it. I also brought six different brands/types of ammo.

    The CZ has a Nikon Monarch 6-24x50 scope
    The Winchester has an old Bushnell 4x38 wide angle scope
    Shots were taken at 110 yards.
    The targets are 6" wide.

    Here is the target with 6 shots from the CZ:

    Here is the target with 10 shots from the Winchester:

    Pretty sad that this old lever gun with an old 4x fixed-power scope out shoots this fancy CZ with a very good scope on it. I will box it up and get it back to CZ this week.

    Thanks for all the help and suggestions.

    ....with a $200 Marlin .17 and a $100 scope ALL your shots could have been in that little gray circle

    Are you lifting your head between shots...when you cycle the bolt?
     
  14. Man....that is weird.
    Did you test the gun before you did the accurizing?
     
  15. Yup. It was fired fresh out of the box after a good clean/lube, etc. For a year and at least a dozen trips to the range it's always shot exactly like this.

    It ships back to CZ tomorrow and with a little luck they can figure it out. I'm sure it'll take a while but I'll keep you posted.
     
  16. Strange, gotta wonder if it's the rifling twist or maybe bore diameter is off.

    Probably bad rifling somewhere in the barrel.close to the chamber




    Savage makes excellent rifles, +100 on that.
     
  18. Dude there is something drastically wrong with either that rifle or the scope. try another scope & shoot at 50 yards. If the same problem continues then call the company.
    I have a Marlin 25MN(.22 mag) that I picked up years ago for $125.00. Using Federal 50 gr ammo I can put all 7 rounds in a 1 inch circle at 100 yards. Now I know that most CZs can at least do that so I know something is just wrong with your rifle or scope.
     
  19. i have a savage model 93, with a cheap bushnell 3x9, i can shoot sub 1" at 100yards, not a bull barel either...love mine...good luck
     
  20. oh yeah, i shoot wichester super X 40 grain hollow points
