My first "birdgun" was a CVA Patriot 45 caliber percussion. It had a short 5 inch barrel. But load that with No. 6 shot and over shot card wads and it was one heck of a trappers bird killer. I carried it on the side of pack basket when trapping. I could reach back over my shoulder and pluck it from the holster whenever a stray partridge would appear.
I use the TC Omega. It's kinda cheatin though I think now because they shoot just like a single shot rifle. Fiber optic sights and the works, never used it in maine but Kansas you can't use scopes on muzzle loaders so it makes it as little more old school I guess. Think I'll use a traditional this year though!
Deer Creek makes an underhammer percussion kit, true to the original 1835 patent, that's available in .45 or .50. Two barrel lengths, 26" and 32", 1:66' twist, available "in-the-white" only. Really easy to finish off, around $250 or so. I have a .36 in it and it's a real shooter. Easy to tune the trigger, I have all the details about trigger tuning and will happily let ya in on my "secret" finishing formula :wink: . Let me know.
Hmmm, I wasn't going to post on this thread but someone brought up the .36 cal. While we do own a pair of CVA inlines, I have (passed down from g. g. grandad) an original 1767 or 1787 .36 cal. I was told the "works" was made by a clock maker way back when. Signatures are ingraved in different places too!
Back to the original question, I just stuff a pair of the smokeless black powder 40's or 50 grains, and a 45/50 sabot on top. It shoots both loads with equal accuracy under 100 yards. The CVA may not clean as fast as the others but mine shoots as good as I need to kill deer.
