Lin, I imagine you will do it and when you do, it will be a beauty I'm sure.
The flintlock and a cedar strip canoe have been on my "to do list" for 20 - 30 years. It'll probably never happen. We do have a builder whom I admire here in Michigan, though, so if I get the coins together before he quits building, at least that will be in my hands. I was planning on a .50 cal, but a smoothbore 20ga with ball would work fine at the ranges I shoot at and with a shot charge, would be a real hoot for small game.
Is that a temper line in that 52100? I thought 52100 was probably too deep hardening for it to show up like that.
