Most of the crimped pistol brass I've come across has been Winchester. The ones with a small cross in a circle stamped on the bottom IIRC.
I just toss them now, but the ones I did fix I just used the case mouth dechamfer tool to remove the crimp. Makes them prime pretty easily with the auto prime also. Slight misalignments become a none issue. Works for the BMG cases as well where almost all are crimped.
