Simple reality.
Been loading 2 different 45acp cast bullets for a while now and have been using exclusively R*P brass on these loading. Well after all this time I finally used up all the hundreds of cleaned R*P brass I had. I just had to try a different brass once again and GGggrrrr. No Go! Stuff may work in the Springfield but it will just not work in my Tanfoglio Witness.
So I guess I will be spending the day washing, sorting, drying and tumbling 45acp brass.
