I have read threads of shooting patched roundballs, and 4,5,and 6 size shot in smoothbores, but have never read anything about buckshot. If I were hunting deer with a smoothbore I would definetly use a patched roundball, but was just wondering what is the largest shot you could shoot out of a 10 to 20 guage smoothbore. May want to try it at the range just for fun. Many thanks.
Experimented at the range one day with a .62cal Flint smoothbore using .440's, then .490's in paper shot cups, limiting the # of balls to keep their total weight within the normal weight range.
The .440s were so small that they stagger stacked at extreme offset angles from each other and when they left the muzzle, apparently took spread directions basede on being stacked with those offsets...typical group at 30yds was 18" and randomly scattered, unusable.
However, trying three .490s, their larger size made them basically stack relatively straight on top of each other and they grouped beautifully...3-4" at 30yds, 4-5" groups at 40yds.
I used 80grns Goex 2F, 2 Oxyoke wonderwads, paper shot cup, 3-.490's, and a circle fly OS card.
The target was stapled to the side of a huge power company wooden "cable reel" and the .490's went through 2" inch hardwood on both sides of the reel...4" total wood.
Didn't try it at 50yds but based on the track through 30 and 40yds, the group would probably be no more than 6-7" at 50yds...a nice group for a deer's heart/lung area if you wanted to try that.
