Thread: 223 brass

I got given a hole bunch of millsurp brass most is boxer primed and the odd one is berdan the crimp dose hold the primers in however it should pop them out with only a little more effort than a standard un-crimped boxer if its not de-caping easy pull it back out (if it don't fit don't force it in other words) I use rcbs dies and keep spare de-caping pins handy but I've never broken one must of resized 3000 once fired millsurps and found 100 berdan primed total you just gotta remember if it fells wrong it most likely is also don't skimp on the lube

if your real worried buy a lee full length size die as the collect system at the top will give (slide up through the screw) before the de-caping pin breaks then all you have to do is losen the screw and reset the pin hight and your good to go
