Did H&R make a 45 cal muzzleloader. I was in my treestand the other night thinking it would be nice to have a 20 inch or so barrel. My ML right now is a Winchester X150 .Great gun, but to long for my type of hunting . By time ML season rolls around in Michigan the dear are real spooky. They re hiding out in the thick stuff till dark. For me most shots are 50-70 yards. I think a 45 cal with like a 20 inch barrel would be perfect. I think my next barrel is gunna be a ML barrel ,hopefully .45 cal & cut it down to 19-20 inches.
