Re: Inside neck reaming

Besides, if you stick a bullet into the UN-sized case and it hits something, well, you got got ya a doughnut! If you seat the bullet into that doughnut, all sorta funky crap will happen to your accuracy.
I get dougnnuts when I fireform Lapua 22-250 into 6xc and instead of cutting them out, which is a PITA, I just throat my bbls a wee bit out so I can seat the bullets out in front of the doughnut and avoid reaming cases. Problem solved. Of course, if you cant adjust your bbl throat, its reaming time. If you have to ream, get access to a minilathe and chuck them up and use a K&M reamer. makes it a bit more bearable, but still a PITA.

Another alternative to reaming, when shooting in a factory chambered rifle, is to merely use a separate expander like the Sinclair Expander die. If one neck sizes with a bushing/shoulder bump die, there is no expander ball on the de-priming rod. The mandrel on the expander die will move any doughnut to the outside of the case. Some will follow up with a pass through the neck turning process to remove the excess metal outside the neck and others just leave it as somewhat of a centering ring, just like partial neck sizing.
Each method has it's own merits in the individuals mind. What's right or wrong isn't as important as what works. If it works for the particular individual so be it.
