[QUOTE="elkaholic, post: 1760025, member: 13833"] About 58 grains but its not necessarily a straight up comparison. IMO, case design changes how powder burns and where/when peak pressure occurs with a given charge. I know this because my 280 Sherman (similar to an A. I.) will not outrun the SS even though capacity is a little more. I think the ss and A. I. are very close to the same capacity but an A. I. will not keep up even though they are both low body taper cases with a 40 degree shoulder. [/QUOTE]
