just got a batch of 200 once fired PMC brass with military primer crimps. I played around with a couple ideas for inexpensive alternatives to remove the crimp last night. I figured out that a counter sink bit works great I fixed up 30 cases last night this way and loaded them up and gonna hit the range in a few hours with them. I dont think im gonna bother trying anything else aswell as the counter sink worked. dont waste your money on anything else a counter sink is just few bucks compared to 20 for that rcbs deal.
