[QUOTE="Broz, post: 866590, member: 7503"] Sure, in the past I have talked to people that have had wrecks with 3 grove jacketed bullets. They were indeed smaller caliber than the .308 but it was our general consensus that some 3 grove barrels leave a deeper inscription in the jacket than 5 or 6 grove rifling. The result could be a jacket that is ready to let go before impact. I doubt the .308 and 10 twist would ever cause the bullet to come apart before impact, but some higher Velocity chambering could. The rifle you are building, I feel would be a great hunting rifle for long range within the limits of the chambering. The 215 works very well on game at lower velocities. I will admit also to not being a 3 or 4 grove fan so maybe that is some of my problem too. My opinions stem from a 4 grove I threw in the trash after much grief, and the fact that the best shooting custom barrels I have ever owned were all either 5R, 5C or 6 grove barrels. This is just my personal opinions and findings. Jeff [/QUOTE]
