Somewhere, there may well have been a round barreled American rifle, I don't say that they absolutely did not exist. I WILL say that IF they did, they would be quite rare. I could show you photos of a German rifle or two with round barrels (and raised ribs... which are SUPER cool!), but it's not exactly the same thing! :haha:
If someone wants to build themselves one, go ahead, knock yourself out. I won't say that it's "wrong", but it would definitely have been considered EXTREMELY unusual at the time. Someone may have done it 200 years ago (and someone else already mentioned military rifles), but it was not the accepted norm. The prevailing style dictated that rifle barrels were octagon. :wink: The original question was were there any round barreled Kentucky Rifles. My answer is very few, IF ANY. Again, smoothbored guns, lots of 'em, but not rifled guns.
Some here have posited the notion of "surely they thought of it", which is very dangerous. It can be, and is, used to justify virtually anything. Everything was invented by someone. The old saw is quite true, there's a first time for everything. How many times have you seen some new invention or something and said to yourself "duh, it's so simple, why didn't I think of that?"? Yeah, why didn't you??? Why didn't anyone else think of it before either? Same thing looking back on the past. Some of the simplest everyday things for us today might seem quite novel to them, even if the materials and technology existed at the time to do the exact same thing.
Of course it's "safe" to give ourselves a little leeway, we don't have to make precise copies of existing artifacts, but we should keep ourselves within the range of possibilities and probabilities that existed at the time, IF we wish to portray something close to an accurate representation of the way things were back then. :wink:
Personally, as a gunsmith, I HATE round and octagon-to-round barrels. Much less pleasant for me to inlet, much more difficult to get sights on, more difficult to get tenons on and get it all lined up. Hate them.
