I am amazed, I got mine about 6 weeks ago, I could have already finished but I'm taking my time and I figure the barrel will brown easier after the 4th (I live in North Carolina)...I built a .54 back in the '80s...It has a 38 inch Rayle barrel, is a great shooter, have killed plenty of deer with it but...It weighs 10 pounds...The local guy that provided the "kit" didn't want to inlet a swamped barrel, so the barrel is 1 1/16 at the breach and tapers to 15/16...Steady as all get out but, when I put the WoodsRunner together to check the balance, I was amazed...This is my first flintlock with a swamped barrel, sliding wood patchbox and a single trigger....My other one is basically a Southern Mountain rifle with a 13/16 barrel, 42 inches long and .40 caliber...
