Cocked&Locked, treasure your remington 45acp shotshells as they stopped making them some years back. I took a few to the local gun club I belong to and tried them out at 15' on some old targets. Respectable patterns and shot density. I was using a 1943 Ithaca 1911A1 and did notice that the crimped portion of the shell would unfold into the throat of the barrel. No biggie really but as nothing broke off the pistol would fire normally. There is a long thread at the castboolits.com where folks who want to make up their own shot loads but using 30-06 cases suitably trimmed. RCBS does sell a die set for making shotshells for either 34 pistol or revolver. Think I have about 45 shotshells left. So maybe I'll have to follow my own advice. Frank
