... with a .257 pilot that I could borrow? Or, maybe I could pay you to do a little outside neck turning for me? Here's the story ... loading for two different .25-284's ... one Winchester and one Savage. Have loaded with re-formed 6.5-284 brass ... some Hornady, some Nosler, and some Lapua ... and with two different sets of dies ... RCBS and Pacific. Especially with the Lapua brass, we can hardly close the bolt on some of them. All full-length re-sized and trimmed to length. I've loaded for that Savage for a while and never had this issue, but was not loading Lapua brass. I mic'd the necks of some various loaded ammo, and it seems the Lapua, in some cases, runs about .010" larger than the others. I also thought about small based dies, but would like to figure this out without a lot of additional expense. I don't just want to throw money at it! Your thoughts?
