[QUOTE="Topshot, post: 557356, member: 13285"] I would say 2850fps with the 350gn SMK would be doable in a 30" barrel. Don't think you would need a 32 as the powder would burn quite well in a .375" barrel. Problem will be getting suitable bullets. Getting reliable B.C. numbers may be even harder as some of the custom bullet makers tend to stretch the truth with this sort of thing. Monilithics may be too long and you would have to have the right twist. I have a 32" long, 1 : 10 twist .375" barrel on order for just such a build. Not sure if it will be a .375 RUM or a Chey-Tac yet but it will be interesting. I plan to try the Rocky Mountain bullet first and also some home made reformed 400grain .410" Woodleigh bullets.
