[QUOTE="highdrum, post: 1575177, member: 13732"] At 110gr capacity, it matches the 300 rum. I haven't heard of a lot of burnt 300 rum barrels in that round count. I think the 300nm imp rifles that were shot out that quickly may have been abused, long hot shot strings poor cleaning etc. My improved version has a 33° shoulder, CIP taper, might have picked up 3-4gr capacity, I doubt it'll have that much affect on barrel life. The sharper shoulder me help it by containing more flame in the case. [/QUOTE]
