Im thinking about a 50 cal and would like to try wc-872 in my 338, its an improved version of the edge. I am trying some wc-860 that i have had forever, it shoots good but is durty and looks like pressure is going to hit before the case is full. I can poor 118 grains in it. Do you think wc-872 has a chance? I like to call them pasture poodles, shot some two week ago. I take to many guns to shoot them, To much packing and unpacking but its fun and there is nothing better to hone your skills then long range poodles.
