The load I'm looking at is 20.0 grains of IMR 4227 powder over a CCI 450 primer, utilizing the Hornady 180 XTP jacketed hollow-point bullet. This load is supposed to be superbly accurate, easy on the gun and the brass, and still pushes 1,450 feet per second. That's more than enough for Deer-sized game animals.
I found this particular load in an article written by Glen Fryxell, and published on the Los Angeles Silhouette Club's website. I'm not a big experimenter when it comes to cartridge reloading. If I find a load that is accurate, and it works well for me in a particular rifle or pistol, I'm done tinkering around.
As soon as I get some rounds loaded up and I get to send some bullets downrange, I'll report back on my findings. I'm fairly sure that Glen Fryxell's load will work perfectly in the big Ruger Single-action.
