Calling Mr Gibson!!
I am looking to use a powder that fills the case better, but still gets standard velocity for the 45 Colt of 800-900 FPS using 250-260 gr bullets. Looking at the Hodgdon website, it shows the max charge of trail boss with a 250 gr bullet is getting under 800 FPS. Looking at the Vihtavouri website, it shows being able to reach 1,000 FPS with Tin Star using a 250 RNFP bullet. I’m not trying to go that high, lol.
What I’m asking is if it’s possible to reach my velocity window with trail boss or is VV Tin Star the way to go?
Thank you.
