.222/.222mag RCBS Neck Sizer on a .223 REM case?

[thomtwo]

This has probably been ask before, but here goes anyway.
Has anyone or can you use a .222/.222mag RCBS neck sizer on a .223 REM case?

I have a new .223 Wylde chambered S/S 18" barrel and a new JP Enterprises BCG.

I haven't fired a round in the new setup yet,
but I'll trying to adjust the headspace to the case shoulder when I have fired case.

I read if you set the shoulder back .003 the round feeds well in an AR.

I'm use to doing this with my bolt type varmint rifles. .220 Swift, 222REM, 222REM Mag,

I'm hoping for the best accuracy possible in this AR setu

Full length size your gas gun brass,setting the shoulder back .002"-.003" dependent on brass manufacturer w/ a set of the CORRECT dies & don't look back.

Your gas gun will throw fliers if the brass is neck sized or not!

get a 223 rem fl sizing die. Bump the shoulders on your brass .003".

I have RCBS FL sizer and bullet seater dies.
I was just trying to get the best accuracy out of this AR.

I have a Browning BAR .270 (gas) that shoots a 1" and less 5 shot group at 100 yrds.

You may want to get a precision seating die, the RCBS std seating die is not a precision seater. You might try a Wilson seater.

I have Wilson bullet seater dies for my .222Mag and .220 Swift.

Any chance either would work with the .223 REM?
