bubba.50, thats my thought on shooting opposite. A couple of guys I know will only shoot single barrel smoothbore flinters. Thanks for the word on Green Mountain. I will look them up. I also know going from a .54 to .45 cal. my Renegade going to pick up some weight, but the lightest Scheutzen rifle I had was a .22 short RF that weighed 10.5 lbs. and I had a Hi Wall with a #5 barrel in .32-40 that weighed 13 lbs. so weight is not problem, course that's been 20 years ago. Saw a nice left hand flintlock target rifle that weighs in I believe I read 13#. It's a recent custom made rifle.
