The only gun I have left from when I used to build guns is a New England Fowler with a 55 inch barrel. I love the gun, but it's hard to shoot because after a shot or two, the heat dissapating from the length of the barrel actually distorts my front sight. I made the sight a small sliver of brass, just like the original. Very low to the barrel. Anybody else expirience this. Kinda makes me wonder if a militiaman was using this type of gun at say Lexington and Concord, it might explain why more British weren't shot that day. The distortion is crazy!
