Lately as I scrounge for cases at my range I have been getting a lot of WCC(Western Cartridge Company) headstamps which you have to de-crimp to use. These seem to have a heavy crimp compared to others I have de-crimped. Is this considered a good case or am I wasting my time with these? Lately I have been just setting them to the side to de-crimp in a big batch(if its worth it). Does anyone else de-crimp 9mm and whats a fast method for this caliber? In the last year I have collected around 10,000 9mm cases so if its not worth it I'll probably just toss them.
