to be fair I think I'm the problem not the die, just need a little help. I have lots of 357sig brass so I grabbed a 357sig conversion barrel and decided I would play. I purchased the Dillon 357sig die set for my 650 and during setting everything up within 4 cases the bushing inside the sizer die came out on a sized case and proceeded on it's journey to the second stage. I was using hornady one shot on the cases (not much but enough to slick em up I thought.) Anyway I notified Dillon and of course they said send it back, which I did. Just tried again, this time I ran the brass through a 40 sizer first to size some and decap. My theory was maybe I could better feel what was going on as I sized this time. first case sized great and went right into my case gauge and back out no problem. second case felt a little harder to size but not much and the bushing came out with it. I've loaded tons of 40, 9, 45, and 38 but this is getting a little crazy any help would be..............helpful.
