This is some load data for the 45 ACP in an Oly AR-15 carbine. I was looking for a load that would push a 230 gr. Plated bullet to speed between 1000 to 1100 fps. Being a port sider I need a load that is clean burning. The Ar-15 in pistol rounds are blow back designs. The powders the I had on hand were: Winchester 231, Unique, AA#5, and AA#7. I loaded up 50 rounds of each, all cases were starline, the primer is CCI 300 large pistol, the OAL length was 1.260. All were loaded on a Dillon 550B. For me the best load was Win 231, 6.5 grs. AA#5 and AA#7 both put a lot of unburnt powder out the ejection port and would hit me in the face. Unique and Win 231 would not put out unburnt powder. All shot into a paper plate at 100 yards, using stock sights. Below are the chrony data for my loads:
