[QUOTE="MontanaRifleman, post: 762741, member: 11717"] I agree that once you start getting extremely overbore, your loss of efficiency goes up exponentially. I think the 300 would serve you better. With the coming of the Berger 195 in 7mm, that may change the picture a little with a good slow powder. If I was considering a 7 RUM, I would probably push the shoulder down to 40* and lengthen the neck to mitigate throat erosion. It is well know for eating barrels quick. A heavier bullet and slower powder would slow that process a little as well. [/QUOTE]
