I ran some numbers on handloads.com website. The differences between an 1800 fps 200g and a 1600 fps 240 g are not that great. Because the bc of the 200 g is less than the 240 g, the 200 fps only gets you an 1" less drop at 150 yds, which I would consider a max range for deer hunting with a 44 mag handgun. The lil' gun powder seems like an interesting option. Anybody use it?
