i have a bunch of once fired brass that i bought that i will be putting through my stainless tumbler. the brass is kind of dirty and some of it has crimped primers so i was wanting to know if i can use my resizing die with the decapping pin run way down so that i can punch out the primers without gunking up my dies before i clean the brass. i'll get a dedicated decappping die soon but i'd like to play with my new toy (the tumbler) this weekend if possible.
