Has any one used RCBS #10501 dies for the 223 wssm. I have some offer them to me when I posted an wtb add on a forum. He also offered me custom .228 70 grn copper jacketed swaged bullets is there any concerns with using them.
Stefan, you've posted this question in a couple different threads. I'm a bit confused? Are you asking if you can use WSSM dies to load 22HP? The WSSM case is 1.670" long. The 22HP case is 2.05" long. I'd say nope.
