Of course, compared to the loads used in military muskets in those days, hitting consistently on that drum lid at 100 yards, was beyond most men and all the guns involved. Seems to me the Brits used a .690 ball and the US were into .640's - for .75's through .80's and .69's through .70's. Also seems to me, that when the US military issued .65 calibre balls around 1820 for the paper ctgs., their hits doubled on the targets of choice - at 80 to 100 yards - the criteria being how many hits on a turkey (target) at 100 yards out of 5 shots - the number with the larger ball was 2 or 3 hits - seems to me.
Nowadays, guys tightly patch the balls and the accuracy improved. Too, we shoot a lot more than any solider ever did, even in war, I'm certain.
At Helfey, for the muzzleloading silhouette match, we shoot steel 'pins' at 25 yards, 'ducks' at 50 yards, 'pigs' at 75 yards and I think it's 'rams' at 100 - all offhand - rams might be turkeys though. We have two smoothbore shooters who almost or do 'ace' the course, every year. There are few and very far between rifle shooters who can beat those two - good thing they shoot in the smoothbore category.
Now, this year - might be different as to scores.
maybe not
as is usual.HA!
