I bought the yukon combo pack last summer to start hunting with a muzzleloader. I went to the range and made one ragged hole with six shots out of ten at 50 yards. The others not in the hole were the first shot and a few others. I settled on 100 grains of Pyro RS and a 240g xtp that came in the combo pack. I also tried t/c cheap shots which shot equally well. These combos are plenty accurate at 100 yards and my shots are always less than 100 and closer to 75 yards. First morning of VA's ml'er season, a spike came in and I let him come to 30 yards before dropping the hammer. He went 20 yards and piled up.

Cleaning is a breeze, with the action dropped the breach plug comes straight out. Barrel is secured to the stock via two screws.

One complaint was the front sight, the fiber optic piece slides into a metal groove. It also slides out, where exactly that happened I am unsure. Mine is scoped and it's not really a concern though.

I looked at the wolf and the huntsman when I bought the Yukon. Either of those may be easier to prime with gloves in cold weather, but it's not cold here in early November and I can still prime the Yukon with gloves (shot it over christmas in PA). The wolf's ramrod ruled it out for me. What made my decision was the Yukon's action, at first I thought it was similar to the Remington Genesis, but afterwards realized the simple design may even be better.

Check out the three for yourself, if it's not a surprise, let your grandson handle them and then make the decision. Any of the three would be fine.

Any of the three mentioned would make a great first gun.
