Not quite sure, but I have a 30.06 that did the same thing...
My Uncle said the bullet was tumbling end over end... It was an old Japanese rifle my Grandfather had re-bored to 30.06, and my Uncle believe it probably had something to do with the rifling job the gunsmith did... I don't know if that's true, but I seen what you are talking about first hand... [sniper2] |

It's called "keyholing" because the result looks a lot like a key hole on the target. I've seen it too, but not with my guns.
What ammo are you using and what is the twist rate of your barrel? |

I believe you are refering to keyholeing (i.e. the hole in target looks like a slash not a round hole). If this is the case it is most likely the weight of the bullet. Most AR type rifles are a 1:9 twist ratio rifling which will only stabilize about 52gr. and heavier projectiles. Try using some SS109 ammo and I bet it will work just fine.
Hope this helps. Sorry about the spelling its too late to think. |

Depends.... Certain bullet weights are made for certain twist rates. The faster the rate, the heavier the bullet.
I don't know the weight of Wolf - or the twist rate of your rifle. |

Keyholing is normally associated with badly eroded barrel throats. Being that your weapon is new we can rule that out which leaves me without a valid response.[:\] However, you should try the following. First make sure you thoroughly clean your weapon and then get ammo from different mfgs and try them. If the problem is still there I would have a gunsmith take a closer look.

Quoted: on the barrel it says 5.45 nato 1/9 hbar [>:/] Only 2 times in 2k rounds tells me it's just the occasional bad bullet. Bullets aren't always up to spec...espcially Wolf. If it was an actual twist rate/ bullet weight problem, it would be keyholing all the time. |

That's a very good point. I know that in my experience I've seen a lot of variation from shot to shot in the Wolf ammo.

Just to give you an idea about what you're getting with Wolf ammo... Open up a box and take out all of the rounds. Line them all up in a row on a flat table and look down the line and see how much variation you have in height. That translates into varying seating depth for the bullet, which has all kinds of accuracy implications. IMO, I really doubt it's your gun's fault. Do what was already suggested and try some other ammo and see if you have the same problem.
