resizing brass

[TimW]

I have an Enfield .303 that I only neck size when reloading, since I am shooting it in the same gun. I was wondering if one can only neck size the brass for a semi-auto (FAL, AR, etc.) if it will be shot in the same weapon??

Just curious.

[Rule .308]

That is generally thought of as a bad idea in auto loading rifles. Myself, I have always used small based dies for my auto loaders and any more you read about SB dies sets being over kill and that regular full length dies being more than adequate. I haven't had any real problems over working my brass, however my partner routinely splits necks in his AR and he uses the same loads and techniques as myself. I would full length size with regular dies and if this doesn't cut it then add an SB sizer to your set up. Rule .308

TimW- Give it a try. Neck size 100 rds and Full length resize 100 more. Mark them well with a permenent marker. Shoot them and reload with same treatment, continue to do this until brass is no longer usable and report back. You will not be dealing with excess pressures only misfeeds. I think that the recomendation to FL resize in semi-autos has to do with the fact that closing bolt into battery is not as strong as a bolt gun where the camming action is greater.

Tim, I've been loading for my Garand using full length RCBS dies with no problems. I use RCBS SB dies for my Mini 14 also shooting those same loads in a borrowed Ar with no problems. A buddy loads for his mini using standard FL dies and has no problems. I'm afraid you may have problems only neck sizing, but the only way to know is to try it. I've not really tried to load any for my l1a1, simply because I can buy surplus ammo cheaper than I can reload it.
