    SR-4759 in .45 Colt?

    Hi,

    I've just recently started messing with SR-4759 for my .45-70's.

    I noticed that Lyman also lists one load for the .45 Colt using this powder. Interstingly enough, in all of my manuals this is the only load shown for .45 Colt with that powder. Based on this alone, I imagine that it's probably not a very suitable powder for the caliber. (I've been using Unique, and occasionally Trail Boss, for all of my colt loads. )

    Any thoughts or opinions?

    thanks,

    Chris.

    Hi Chris, I see SR-4759 listed for several bullet weights in my Speer#13 loading manual, but it's listed in the "Ruger & Contender loads only" section. What revolver were you going to use?

    It wouldn't make much sense in a revolver (or anything with a short barrel) but in a rifle it might do quite well. As slow as it burns, you'd need at least 16 inches of barrel to give the powder a chance to burn thoroughly and build up some pressure and velocity.

    Oops, I've got that manual too. I guess I didn't look in the Ruger & Contender section. The loads would be for my 1894 Marlin :-).

    I use it for 300 gn loads in the 45 Colt. It's a real slow powder for handguns. You need a big bullet and a good crimp to burn it properly.

    At the mild SAAMI spec pressures for the 45 Colt, it's rather unsuited compared to what else you could be using.
