[QUOTE="Guest, post: 158066"] [b]Re: 22-250 witha 8\" twist[/b] [ QUOTE ] I have found that number of rifling has been more important than actual twist rate when getting the heavy Berger bullets to stay together. All has to to with bullet baring surface compression. Make sure the barrel your getting is not a 3 groove design. A 5 groove is better and a 6 groove would be the best. The fewer the lands in the rifling, on average, the wider the lands. This is what causes the problem. Make sure your getting a thin landed 5 or 6 groove barrel or you will tear the Bergers apart no matter what velocity you are driving them to in a 3 groove barrel.
