I have a CZ-550 in .30-06. It had less than 500 rounds thru it. My problem is at 100 yrds from a bench with sandbags, it will put 2 rounds within .5 inches and put a round 1.5-2 inches low and to the right of the other two. Sometimes the first round is the flier, sometimes the secound round, sometmes the third. It does this with both factory ammo and my reloads.I bought the rifle new and have never fired more than 3 rounds without letting the barrel cool off. I can't find anybody locally who has ever heard of this problem. Someone suggested recrowning the barrel. Anyboby seen this problem before? Thanks.

I would suspect a stock bedding problem.

Uneven forearm pressure, and the barrel is not returning to the same place every time.

Try running a dollar bill down the forearm channel and see if you can locate a tight spot on one side or the other.

A bad crown would cause uniformly bad accuracy every shot.

RC, the barrel is freefloated but the action is not glass bedded. Common sense seems to say you are on the right track.

It could even be the torque on your action screws, I have a .223 Savage that is notoriously bad for this same problem... just haven't had time to pillar and glass bed the action yet but by adjusting the torque on the action screws I can get it to shoot really really well.... like under 3/8" from it's previous 1-1.5" before tightening the screws.

Of course your scope crosshairs could be jumping around to , typically happens if and when you are at the end of your adjustment range. What kind of scope do you have.

[Ky Larry]

BH1, I have a Nikon Buck Master 3X9.

[Birdhunter1]

How much have you adjusted it in elevation or in windage to get to your zero? The Buckmaster's is a good scope and should hold up fine on your rifle, but if you have adjusted it to it's outer limit's it can do this. My guess on your rifle would still be the torque on the action screws or a severe case of copper buildup.

Others will correct me, but I've always thought of recrowning as a fool's errand. Sans some obvious damage, there's just no need. A friend of mine had a Carcano [sic?] that would keyhole at <50yds. The crown looked like it "might" have been the culprit. After recrown, it keyholed at <50yds. :rolleyes:

"... it keyholed at <50yds..." Very likely a shot out barrel or undersized bullets. Maybe just terribly dirty, but clean it and slug the bore. Recrowning isn't going to fix a bad barrel.
Ky Larry, shot flying around like that is most likely the bedding, but the ammo could also be the culprit. Is the rifle scoped? If so, what make? Could also be the operator though. Make sure all the screws are tight and ask somebody else to shoot it.

The 6.5 mm Carcano uses .268 diameter bullets. Hornady makes the 160 grain .268 bullet. I sometimes deer hunt with my Carcanos and that is the bullet I use.

I have a CZ rifle in a 204 Ruger. Had the same problem as you. I found that the stock was not inletted correctly in the receiver area. When stock screws were tightened, the action could still move in the stock. Glass bedded the action. Problem solved. Rifle is very accurate now.

[Ky Larry]

Thanks for your suggestions. I think I'll try glass bedding the action.
