Hello
My favorite rifle for hogs is a 356 Winchester Marlin 336. I run 46.5 g of tac with a magnum primer and Speer 220. At 47 my primers started flattening and got a donut around the strike. I use cast 357 mag bullets also. I'm running low on brass and wonder has any one actually formed any brass from 308 or used 358 brass? I made a few from 308 just using my rcbs die set. Seems easy enough. I only loaded 42 g powder. They cycle but haven't fired yet. Also wondering if with similar charge is poi going to change with different brass. Could relegate the 308 to the cast bullets as a worst case scenario. Anyone e actually do this yet? Josh
