I second what was said above. I have always liked heavy hardcast bullets, as they ensure good positive penetration. There is nothing wrong with jacketed expanding bullets on some of the lighter game animals, but with larger game, you need a little more with the .44 Magnum. You have enough diameter as it is with a .429" hole, so the only thing you really need is a bullet that is going to go through the vitals without question.
Randy Garrett has taken this concept to the extreme with some of his loads, and offers some true heavyweight loads in various calibers. Please understand these loads are not for the cheap minded or the faint of heart. Recoil is stout, and a box of 50 rounds will set you back better than $50. You can reload for much cheaper, as harcast bullets in almost any imaginable weight are available through a variety of vendors. Personally, I would stick with 250-300gr bullets over H110, as it has always been a solid performer.
S-Sheriff,
How much luck have you had with WC-820? I picked up a pound through a friend of mine, and I have read that you should use AA#9 data. I have also read that some lots have been closer to #2400, and heard still that H110 data is the one to follow. What has your experience been? I would like to load some 240gr hardcast bullets over this powder to use in my 7.5" SBH and 10" Contender, and would like to reach around 1200 fps (nothing too hot).
