[QUOTE="Lefty7mmstw, post: 2670071, member: 48043"] I wouldn't go short freebore on a 7rum. I have one built for around a 3.8" cartridge length with 175 eld-x pills seated to 3.670". I'm running powder charges more akin to a 7mmstw than a 7rum. 86 h50bmg with the 175 eld-x produces 2900 fps from the rifle. I suppose I could push faster, but I've already blown a couple cases with book loads with powders like rl25 and retumbo. I went with h50bmg to get the load density up to a usable level as the reduced charges with some of the faster magnum powders would have fallen below 80%. That's a bit low for consistency in this case size. [/QUOTE]
