Yes, the muzzleloader we have is a .50 cal Remington 700. For me I put 90 grains of Pyrodex in it and use Hornady sabot's w. a .45 jacketed hollow point bullet. Back when I originally sighted it in I could cover 3 shots with a quarter at a little over 100 yards. Since then I just shoot it once or twice at distances under that to make sure it's still on. Jenna was able to keep about 3" groups with it at about 60 yards the day she gave it a try. Was surprised at that distance the real light load only dropped less than a couple of inches, the 70 grains shot just as good as the 90. It's a pain to clean but it's very reliable (knock on wood! :smash: ) and accurate!!
