Re: neck turning tool
Hey guys, this may or may not be needed, but since it was mentioned and I didn't see any clarification, I thought I'd chime in here for a moment. In re the comment about inside neck reaming, we're talking about something entirely different here. Inside neck reaming is done to increase clearance, and WILL NOT UNIFORM the brass, unless a very specific die and reamer are used in conjunction with one another. This isn't normally the situation, so it's most likely that if you had a concentricity problem before, now you just have a concentricity problem with thinner neck walls.
Inside neck reaming is a viable and useful operation, but it's best application is to reduce excessively thick necks that have resulted from necking cases down to a smaller caliber (30-06 down to 25-06, for example). Necessary at times, but for entirely different reasons.
Outside neck turning can be used to reduce neck thickness, but its primary purpose is to clean up those nasty concentricity problems. Two totally different animals, and they shouldn't be confused. Hope that helps,
