I bought a set of used 32hr lyman dies.whoever owned them before,knew what he was doing.the set came with a .308 expander,and a .3105,,with a rcbs 32acp seater die.anyways,,the 311316 that mikes .311,,seated with very little neck tension,but crimped beautifully in the old rcbs die,
Ive had bad luck with es with this cartridge,,150 es 60sd,,is common,,these dies cut that more then half!!today was between 16-56 es,,and shot some splendid tight groups!!
Very happy camper tonight!!
That 311316,,is .003 undersized,,rattles out the throats,and down the barrell,and shoots 12-1250 fps,,and clean,,not 1 speck of lead anywhere,,this shouldnt work,but it sure enough does!!
Even the sweet rcbs 98swc loads,tightened up a bit,with these dies,and es nosedived!!

The bullet starts out .003 under, but once the big light comes on behind it, it's probably not undersized when it hits the forcing cone! Dynamic fit, it's a wonderful thing.
