[QUOTE="watersfam, post: 2238764, member: 118754"] So the 40 Hornady +P cartridges fire formed perfectly. A box of 1980's-era Winchester .257 Bob cartridges had all but one form out perfectly. Unfortunately the one I fired off that ruptured, did something to my ejector pin on the bolt (it appears to be stuck in the housing). I also acquired a complete box of .257 AI reload cartridges that had already been formed. The posts that talk about differences in milling chamber shapes were correct. Every one of these stuck in the chamber and had to be popped out with a ramrod. None of them ruptured, but you could tell that the reloaded AI's I shot through my rifle were "pushed up" or formed out a little above where the AI cartridges were before I fired them. [/QUOTE]
