[QUOTE="Mikecr, post: 9157, member: 1521"] There is every bullet/twist combination possible out there in STD 308s. I've never heard of a 308 burning out this side of several thousand rounds. If I remember correctly, the 6PPC also offers a long barrel life. No matter what you do with them, they will last longer than a 240gibbs or a 30-378. And no matter you do with a 30-378, it will not last as long as a std 308. Much as I hate it, the erosion definitely follows the amount of powder set loose in a given bore area. Pressure, boattail, powder type, dwell,etc, must all have minor roles, as neither, or all, cannot contradict powder AMOUNT away. In otherwords, a 56grcap Win308 at 60kpsi pressure load will still outlast a 133grcap 30-378Wby. Even if it's loaded to only a 40kpsi pressure load. I don't understand why. Simple energy amount, I guess. [/QUOTE]
