The cartridge I shoot in F-open is a round designed for long range hunting by a couple of die hard elk hunting, cartridge wildcatters. I can't recall Rich's partner in crime but Rich Sherman put the name to the line of cartridges based off of the Remington 7 SAUM. It is basically a shorter bodied 7 SAUM with a longer neck to keep the boat tail of the higher weight .284/7mm bullets out of the engine room to maximize powder capacity while keeping the OAL of the round to allow cycling in a short action rifle. The thought is to have the faster, easier cycling that a short action affords for possible follow up shots and less weight for mountain rifles. A couple of F-class guys also, at the same time, were attempting the same thing only because of the efficiency of the shape/volume of that case for 7mm heavy bullets. When I also discussed wanting a similar cartridge, a fellow competitor suggested giving Sherman a call as he was producing chamber reamers, sizing dies, and headstamped brass for the cartridge he called the 7 SS Mag. I pioneered its use in F-class now many others are finding success with it using the 180gr Berger hybrid. It would make a hunting round, with the proper rifle/optics, that I would not hesitate to make an ethical 800yd shot on an elk if conditions and my position were solid.
