[QUOTE="comen, post: 2560415, member: 52622"] I use the COW method, although I prefer coarse cornmeal, or grits for filler. For powder I use Unigue and vary the charge by case capacity. to form 240 Gibbs and 6.5 280AI I use 14 grains. I fill the case to the top with filler, and finger press a dental wax plug (.035"0 cutting it in Place with the mouth of the case. For cases that require a very large bore increase, my Gunsmith builds a fireforming chamber from drill steel using the chambering reamer, and turns the OD into a 12 Guage shotgun case that drops into a 3" chamber. I do my .411-284 wildcat this way with the COW method and blow out the neck to full diameter in one shot with no barrel wear at all. I form my Gibbs using 270 win cases necked down to fit the chamber, and trim after fireforming. [/QUOTE]
