Yes...very long-barreled. That’s one reason that they were not good field pieces. Some were .60 cal, but the American frontiersmen often used smaller calibers so they would need less lead. And I imagine they kicked like a mule (esp. the .50 and .60 cals).
I shoot these rifles every week and hunt with them. They do not kick bad, more like a hard push.Black powder burns slower than smokeless so the recoil is not as sharp.
