[QUOTE="chuckhammer, post: 1044670, member: 25816"] I came up with a wildcat 7mm on an improved 300 Win Mag case that I call the 7mm Valkyrie. Minimal body taper and a 37 deg shoulder. Case capacity is 93 grains of water with WW Super brass. Loading to .020 off the lands with 87 grains of RL33 moves a 180 Berger Hybrid at 3300 from the muzzle. Case heads show light ejector marks. Extraction is easy. 28" Criterion Match 1/9 on a Savage 110 receiver. Far as I can tell it very closely mimics 7mm STW ballistics on a shorter case. Maybe next time I'll do the same thing with the STW itself. Would match the 26 Nosler capacity. :-) [/QUOTE]
