Does anybody have info for the maximum velocity that a Berger bullet can be pushed to before coming apart? I know that twist rate has a hand in the outcome also. I am shooting 180 VLD,s at 3334 fps average with a 1 in 9 twist. I am having what appears to be bullet integrity problems at this velocity. I have called and talked to Berger but can not get a definite answer from them. I was just wondering if anyone has had any problems or experinces that they can share.
