I picked up a 7mm vom Hofe. A 7mm based on a shortened .404 case long before anyone else thought of doing such a thing. It fits a standard action. The ballistics are on a par with the 7mm STW and this rifle (a Mauser 66), will shoot 3 Accubonds into one tight ragged hole at 100 yards. It seems to me that, the 7mm STW is simply reinventing the wheel, but the longer case means a longer action and more powder besides. These aren't exactly improvements!
