The 500 38's I have are all mixed brands, tumbled, and some are de-primed. I haven't even busted open the bag I purchased 2 years ago when there was no 357 to be had. In desperation I made a knee jerk purchase.
I'm not looking for any specific used cases as they will be used for range practice. If I could get a bag of 357's for my 38's I'd organize them by maker and then stuff them with hard cast.
I already have about 350 brand new cases (200 Winchester nickel cases and 150 Remington brass cases) that I'll be loading with some personal defense loads while I work up a favorite.
