Jingles Christmas but you guys are impressive with your numbers. All I ever did was never run all the way through a piece of cloth, have a couple of thicknesses on hand, and just get my whatever load to crack like a whip and give me them pretty little red dots in the barrel after a shot. I suspect that the thicker cloth always helped and I never needed more than five rounds to group once I had my sights set after the gun was new.
I always did it that way because I wondered what life in the forest was like when people could not go off to Joanns or use micrometers.
I betcha you guys who can ding Tootsie Roll Pops on a trail walk with all your tech and physics are every bit as good as those guys in the 18th century we all wish we could talk to. If there was ever a shooting contest between todays riflemen with our guns and those souls who made our history, I'd hate to have to live on the margin.
Don't shoot yore eye out, kid
