Home Forums Hunting & Shooting Ask The Gunwriters Ruger M 77/357 rebarrel to 256 WinMag?

I was never able to get the 75grn Speer or the 86grn Rem bullets to expand at 25-20 speeds. The 70grn blitzkings certainly do expand, but with the low speeds of the 25-20 they hold together just fine. That bullet has a lot of empty jacket that upsets easily enough causing a fairly wide mushroom.
