I was working up some 380 loads for my wife and hand primed them with CCI 400 (small riffle) instead of CCI 500. So I thought I would ask the stupid question. should I just use them knowing they are harder and burn faster or deprime them (about 300). The thought of depriming that many live primers isn't exciting. The only things they would be shot out of are all Hammer fired pistols. Let me know if this mistake has been made and didn't have a problem. I am leaning towards depriming. Wanna kill these ads? We can help!
