I occasionally put together some +P 45 Colt loads. I prefer AA-9 powder for that purpose. In a strong enough gun you'll get the most velocity with W-296 and H-110 powders. But those two powders don't perform best in the 45 unless loaded at or very near maximum for, Ruger Only", loads. AA-9 is more tolerant of a wider range of pressure.
