While reading an old book on grouse hunting, I read that the author's favorite load was 1/2 ounce of #10 shot, with 3 drams of black powder in the right barrel.(muzzle loader)
With 1 ounce of 8s in the left.
He was a sportsman who only would shoot flying birds.
How far away could he reliably kill a grouse with #10 shot?
Why did He use only 1/2 ounce? Why would He use #10 shot in the first place.
