Hello, here a similar rifle in an exhibition in a museum in my hometown Monty
Talking about barrels, and types of rifling, there are two things I would really like to have before I hang up my shooting bags once and for all. 1st is to try some shallow, straight rifling in a " smoothbore" . I have read about it helping with both shot patterns and shooting ball.2nd, I would love to play with something like this example from the 1765 era , with a heart shaped bore. Just for fun !
