I had no idea this would create such responses. My post was simply to let people know that certain primers are much better at handling certain powders and heavy charges than others. If you took it as an attack on your chosen primer, I'm sorry.
During my .270 WSM load Development, I found that, my groups, shrank by about, a 1/4 to 3/8ths of, an inch at, 200 Yards using, the F-215's over, the Win Primers ( using, IMR 7828 Powder ).Any issues running these in some of the short mags?
Uh… you made no mention of small or large primer brass. So when you mentioned 215 primers I assumed it was large rifle primer brass
