I have a 15" RPM Hunter in .358 Winchester with an RPM brake that was built for me by Jim Rock. I subsequently returned the gun to Jim and had him cut a rim on the chamber and modify the extractor to accommodate the .356 Winchester rimmed case. Either cartridge can be used in this gun by changing the extractor, or by using a "Merrill rod". Recoil was not bad with the brake and the design of the grip.
