From the Rainier Loading Manual, 45ACP using the 185gr FP bullet, COL 1.275, Remington primers, loading is to average max pressure 21,000PSI. Showing max loads only in this post.
Blue Dot-13.0 grs 1062'ps
Bullseye-7.1 grs 1069'ps
Unique- 8.4 grs 1064'ps
HP-38- 7.8 grs 1059'ps
HS-6- 11.2 grs 1084'ps
231- 7.7 grs 1053'ps
If you're just looking for plinkers, I'd start by reducing these loads by 20%. If you just want to use Red Dot, my brother loads 5.0 grs under a Speer 185 RN. There's little recoil considering it's a 45ACP. Velocity is just under 900'ps. Lyman shows a max load of Red Dot under a 185 jacketed as 5.5 grs with start loads at 4.5 grs. You can use jacketed data with a 45 ACP. It doesn't have enough velocity at max loads to make a difference. As long as you keep velocities below 1300'ps, the plated bullets are good to go.
