Need a little help with neck sizing

yorker · #1 08-20-2009, 07:50 PM

I have a 30-378, I have been neck sizing the brass and has been shooting superb, now when I neck size it the bolt has a little resistance when closing it. I am guessing this has to do with the shoulder, but how do I get rid of that resistance without resizing my case? Any help and opinions would be greatly appreciated.

Well you have 2 options
1) Resize your cases a little (bump the shoulder back .001" or so)
2) Buy new brass

I guess there is a 3rd option, you could always move the barrel forward .001"

Thanks for the chuckle, the 3rd option amuses me.

I having redding three die set, what is my best option for bumping the shoulder back? Can I do it with the neck sizer?

Thanks for the quick reply.

AJ you've got way to much time on your hands.

You were on a roll with the first two suggestions, but this one might be a little over the top......LMAO though.

Earl,

I use the full length sizer to bump the shoulder. Put the die in until it hits the shell holder, back it out about 1/16", try resizing one, measure the case, if no shoulder movment turn the die in a touch and try it again. Repeat until you get to the point where you are just moving the shoulder back .001 or.002.

Use your body die, or Full Length (FL) die if that is what you have. This will let you push the shoulder back. Make sure to lubricate the brass good. Let us know which die you have, as the directions for setting them up are a little different depending which dies you have. You will resize a little bit at a time until it will just chamber without the binding you are feeling, you will be adjusting the die 1/10 of a turn (or less) once you get close.

+1 WinMagman, you beat me to it. If he is using a full length die, he might want to remove the depriming pin and then neck size with his neck sizer once he has pushed the shoulder back.
