[Unclenick]

You'll find out. Most people only get small base dies if they encounter feed problems. Usually, you won't. The bolt gun, if you don't use its magazine, but single-load, will probably shoot more accurately for you if you neck size its fireformed cases only. That means keeping its cases separate. You can get special neck sizing dies, like the Redding S dies or the Lee Collet die (a good and economical design). Some people compromize by just not pushing it far enough into the sizing dies to hit the shoulder of the case. This leaves a short stretch of the neck unsized near the shoulder, but that can help center the bullet in the neck portion of the chamber, so many consider it desirable.
