A few years ago, before I got my GPR, I was looking at a Canoe Gun kit. I like the looks and proportions.
Not long afterward, having not yet deciding on anything yet, a couple of shooters at my range were shooting black powder, so I went to watch. One had a Brown Bess, and was drilling milk jugs at 100 yards with it. The other had some kind of Fusil with 20+" barrel and he was good for a lot of near misses at 50 yards at a gallon jug.
They said the short barrel, while it's the better looking of the 2 guns, was a big disappointment. He tried wads and shot next, but only 2-3 pellets hit the jug at 25 yards.
Performance made me decide on a rifled barrel, vs the better looking Canoe Gun.
I do have a .62 cal Fusil on order, and should have it in another month or 2. It has a 36" barrel, so will be handier than a Bess, and still maintain reasonable 100 yard accuracy.
