Please ignore the first post. Honestly you need a good reloading manual or receipe book. Please don't listen to people in a forum where some will answer with anything. Many here are knowledgeable....but,this could be dangerous for you. Go by a good manual.How much 231 winchester powder do you use when reloading 300 grain HP/XTP 45 Long Colt bullets?
Ignore any answers here, get a good reloading manual, and don't injure yourself or others. 231 is a fast burning powder recommended for light handgun loads.
You're better off with 296 or H110. Depending on the gun you're firing it from will tell you what data to use.
In or for what gun?


That cartridge is chambered in a wide variety of guns


with widely different pressure limits.


Brian Pierce, of 'Handloader' Magazine recommends


7.1 Gr of 231 behind a 250Gr cast bullet for a 'smokelss era',


Colt S.A army revolver.


This should be safe in anything but an antique.


231 might be a bit 'fast' for a 300 Gr jacketed bullet.


If it's the only option, for a 300 Grainer,


M.R Smiths reloading page recommends . 6.0 Gr. for 630 FPS.


I'd 'step back' to 4.5 Gr. and work up.


You'd be better off using published loads chosen to match


the pressure limits of the gun you're loading for.


Some modern heavy frame revolvers can take higher pressures,


but don't go messing with 'Elmer Keith Loads' unless you know what


you're about.
It should be obvious why it's not a good idea to ever use reloading data from an open forum like this.
I wouldn't. It's a bit too fast-burning for such a heavy bullet.
