.45 ACP revolver. The goal was to shoot a 250 gr. cast bullet to same speeds as typical .45 Colt.
I intend to use the .45 Special rounds in this ACP revolver.
Using 5.8 -6.0 gr. of Unique I was happy to see an average speed of 856 FPS which is right on target for a .45 Colt load in the small frame Colt type revolvers. Being that this is a Ruger .45 ACP revolver it can handle upwards of 21,000-23,000 PSI or this same bullet at 920 FPS but I will keep the load at 6 gr. of Unique.
With the target set up behind my chrono which was about 16 ft distance you can see a nice group. Later did a bit of longer distance
plinking with what was left of the 20 rounds I had to test.
All looks good to load up the rest of the batch! Loading these saves me 2 gr. of powder per round compared to same load in .45 Colt at 8 to 8.5 gr. of Unique...200 grs. saved per 100 rounds loaded!
