I need some help understanding what im reading in various threads. I see a lot of back and fourth which is better from a forming standpoint. They seem to have identical performance. I see the argument being made that 20tac dies are expensive and 20prac only requires bushing. This is true assuming one already had a bushing die? Since I dont have a bushing die im looking at a $120 redding die, the $20 decapping assembly for .20 cal, and the cost of bushings. I see hornady has a $60 20tac die set available… both use 223 as parent case, 20tac has sharper shoulder and longer neck, should require less trimming and maybe slight edge in accuracy. so what am I missing?
