Re: Moving Shoulders on a Case

I'm in the same camp with "dwm" with regards to only sizing the base & neck and not touching the shoulder. Only differance being is I use your standard FL sizer dies i.e; Lee & RCBS. My experience in nearly thirty years of handloading has taught me to leave the shoulder alone after your brass has been fire formed. This practice has proven to virtualy eliminate case neck run-out provided the chamber has been cut straight. It also reduces case stretch keeping it to a minimum extending brass life ten folds. This has helped close my groups by 30% in most cases.

However, I would not advise this practice if you're one to load at or even near max recommended charges unless you were absolutely sure what your rifle has for headspace at the bolt face or firing pin plug. I should also mention I only do this with bolt action or break action rifles. Lever actions and semi-auto's, where match grade accuracy is very rarly achieved, I will bump the shoulder back .0005 - .001 as they tend to need this extra clearance.
