[QUOTE="AZShooter, post: 2690330, member: 5219"] I know that a 3 groove 1 in 7 twist will cause Berger 180 VLD hunting bullets to come apart due to the throat getting worn and combined with that fast twist. This happened in two barrels: 7 STW in just over 100 rounds. 7 Rem mag round count 175 Switching to 180 target with thicker jackets allowed the barrels to shoot for another 75 rounds or so, then the bullets were again being damaged with poor accuracy. That barrel worked well with the accubond and TTSX after throat was worn enough to destroy the Bergers. [/QUOTE]
