I think Jim Kibler has the finest kits for making flint longrifles. His kits, his latest offerings are wonderfully easy to build. He uses state of the art CNC computer driven equipment that makes it a snap together assembly. No need or very minor inletting, a few final work on the metal work and just finish the wood. He has many Youtube videos to walk you through the process.
I am a stickler for authenticity and his creations are really true to form. For less than $2,000 (or less) you can complete a rifle that rivals custom rifles. See my Woodsrunner I built with the "extra fancy Maple" even the carving is done by computer.
Got a message from Jim Kibler, he found a special Maple log that has wood better than his "Extra Fancy" which is 90% curl. The new wood is 100%. He calls it "Select Maple." There are (were) 15 blanks for Woodsrunner and 20 for Southern Mountain Rifle SMR.
I immediately jumped in and ordered a SMR .45cal in "Select Maple." It may be here in a week or so. I can't wait!!!
Plan to build with photos.
Here is a photo from Jim's website. I call it "Embryo."
