A. While the 200-grain truncated bullet is probably sold by everyone who makes cast bullets for the .45 ACP, the only listing I’ve ever run across for the Penn bullet was with Accurate 100, No. 2, No. 5 and No. 7. There is a slight weight/capacity difference between Starline and other brands of brass. You will have to start with slightly reduced loads anyway, just to make sure you are on firm ground. For the most part, data listed for any 200-grain truncated cone cast bullet will be applicable for the brand you have, assuming you start with suggested starting loads and work up. The Accurate loads for the .45 ACP are listed on LoadData.com. I wouldn’t assume you can interchange data from ACP to AR brass, but it is within a couple of grains or so with most brands of brass. - Dave Scovill
