[QUOTE="jwp475, post: 204429, member: 3776"] I don't think that an Improved 300 Rum will gain enough aditional powder space to make much of a difference. A 10 percent increase in powder capacity will give a 2 1/2 percent increase in velocity at the same pressure. The RUM case doesn't have much taper to begin with. You could install a longer magazine and seat the bullets out farther and gain a bit of capacity that way. That is what I did with a 338 laupa I had a detachable box mag installed that allows me to load to 3.885" COAL insted of 3.6"... [/QUOTE]
