I'm looking at possibly getting a new lever gun in .444 Marlin, .450 Marlin, or .45-70 for black bear hunting in the east. Lots of brush. I've shot a .45-70 rolling block or falling block (can't remember which) at the range, and really enjoyed it, but I've never shot the .444 or .450. Just wanted to get some feedback on the velocity, accuracy, stopping power, recoil, and muzzle blast of each of these three rounds, as well as the ammo availability and cost of each. Thanks.
