Alliant 2400 powder

Alliant 2400 has a new look (see above) with the same great powder inside.

If you have any experience with 500 S&W Magnum you know how intense it can be. If you really want to enjoy big-bore magnum revolvers, down-loading to reduced power is a great capability. With lighter bullets and reduced powder charge, you can transform a 44 Magnum or 500 S&W Magnum from a “bucking bronco” to a “tame pony” (or close to it at least!).

Load data from video:

Use load data at your own risk. Ultimate Reloader is not responsible for errors in load on this website. Always cross-reference load data with manufacturer’s published data.

Just be careful when you load reduced loads with any magnum powder as you can lose efficiency (quickly) once you get below the optimum charge weight range. In this case (see load data above) I decided that 70% was the cutoff point, but for future loads I would load in the 80-90% range for 500 S&W Magnum with Alliant 2400. The reason being, below 80% you’ll start to get unburned granules of powder and a dirty burn. I actually went WAY too low in charge weight, and ended up sticking my first bullet in the bore. Whoops! Fortunately it was an easy extraction with a brass punch and some careful tapping. Lesson learned, and now I know what range my 500 S&W Magnum will shoot cleanly with Alliant 2400!
