My son wants a flintlock in a year or two (well, he wants it now, but he'll get it when I say so), so I've been looking at similar barrels. A-weight Rice Transition (38"/3.1 lbs).40 or .36 (4.14lbs -- I have a .40, so he will too, most likely) is the most interesting one I've come across so far. Probably other makers can provide a similar barrel. If he doesn't like or gives it up someday, I can probably use it for offhand in my old age when my shoulder finally gives out too much to shoot my current .40!
