[QUOTE="azsugarbear, post: 1840370, member: 4809"] I have found that a fast twist barrel by itself is not a factor in bullet degradation, but rather a combination of fast twist coupled with high velocity. I have personally witnessed cup and core bullets disintegrating after leaving the barrel in my 270 Allen Magnum. In testing a new bullet I thought I was missing the target, so I kept moving it closer to see where the bullet was hitting. Finally, at about 30 yds. I saw a target that looked like it had been hit by a shotgun blast. The bullets were coming apart after leaving the barrel, spewing pieces of brass and hot lead down range. [/QUOTE]
