Some times...when you use an 8 twist...and you get more RPMs out of your bullets....the A-Tips like to explodicate.....Poof...and now they are gone. Also...my personal testing shows that the 250's aren't good for the 300PRC....You just can't push them fast enough to out do the 230's.
I take it you’ve seen the a-tips explode in flight. I have seen references here and other places on the net that Hornady says not to exceed 290,000 rpm. 2,900 FPS ,for example, using the 230s or 250s in larger 30 cal magnums would seem reasonable. This would be approx. 260,000. What velocity in the 30 cal a-tips have you seen these explosions? Thanks for the help.
