My mold came in today. It is a Lee 452-252-SWC. I cast a few with # 2 alloy that I had left over from my 45-70 500+ grain casting. I used those in a Winchester high wall browning replica. The bullets were shot at 1250 fps over Swiss 1 1/2 black powder. Lubed with Shavers lube, no leading and was very accurate. I am going to shoot these in a single shot Chicopee rifle that I am building chambered in .45 auto rim. The barrel is 24" long from green mountain with a 1 in 16 twist. I want to use 231 powder because I have some and use the Shavers lube. How will the load work?
