You shouldn't have any problems in the 45 acp. I have used them in 9 mm with Unique. The load happens to be the starting load for the Jacketed bullets but is what shot good. I have also used them in 38 special, light loads for 30-06, and I think 44 mag but will have to check my notes.
From there website,
We, at Rainier Ballistics, recommend using lead bullet load data when loading our bullets. There is no need for adjustment when using lead bullet load data. Our bullets are jacketed using an electroplating process and are softer than traditionally jacketed bullets; hence the recommendation to use lead bullet load data. If you only have access to traditionally jacketed load data, we recommend reducing maximum charge by 10%. A roll or taper crimp may be used with our bullets; do not over crimp.
and this is in FAQ
Q3. Do your bullets have ANY velocity restrictions?
A. In general, our bullets typically perform their best when shot at velocities no greater than 1,200 to 1,250 Feet per second (FPS).
