Bullseye was the original 1910 vintage powder used in the 45ACP. The load was a 230 FMJ at 800 fps.

Bullseye is still an excellent powder in the 45 ACP.

I don't have data with 230 FMJ's and Bullseye. A load that a Bullseye shooter was using at the range was 5.0 grs with a 230 FMJ.


I did my load testing with 230 Lead bullets. My data is below, for reference. My next batch will be 4.5 grains with 230 LRN.
