I've shot a 62 cal. 20 guage flinter for the last five years. Roundball as well as shot.
Personally, I feel it is the all purpose gun as I can take big game as well as small.
I have a Chambers .62 Virginia smoothrilfe that I am very fond of, it made one of the final two spots on the wall as I am working down to two guns.out to 60 yds this gun will shoot for me as well as I can do with a rifle.
Not yet, but I just sent off a new .62 GM smoothbore barrel to Ed Rayl to have it rifled. (Thank you very much!) Hopefully I'll be using it next fall on a nice Roosevelt bull.
