I finally was able to round up some brass and put some loads together for my SRH in 44 mag with a 7 1/2" barrel. I wanted to try both W296 and Alliant 2400. I couldn't find exact load data for these bullets, but I found loads on Hodgdons website for 325 gr boolits showing 20 min and 22 max with 296. I loaded up 5 rnds at 21.0 grains with a heavy crimp. Then I found on a reloading website a load of 13.5 grains of 2400 for a 310 grain boolit. After checking around a bunch of other resources, 13.0 seemed like a good safe starting point.
I fired the 2400 rounds first and 5 shots averaged 1030 fps and they shot about 7-8" high at 20 yds. Then I shot 5 rounds of 296. These were about dead on at 20 yds and averaged just under 1350 fps, with significantly more recoil. Brass came out easily, but didn't fall out, same as with the 2400 load.
My question is can I safely bump the 2400 much higher to get it closer to 1200 or 1250? If so how do you think that will affect the point of impact at 25 yds?
Or do I stick with the 296 since it seems to be a good fit at my starting load for both speed and accuracy. I may want to carry this pistol in winter on my dogsled or snowmachine so Im wondering about issues with 296 having squibs at low temp. Plus 2400 meters way better for me in my measure. Should I make a separate summer load and a winter load?
Thanks for any input.
