I'd popped about a dozen pans full of powder at home just to see if the saw cut agate furnished with the rifle worked, and if the lock worked OK. But this was the first time putting a load down the barrel. The first five shots were at
50 yards with 85 grains powder, a Wonder Wad over the powder, followed by a patched ball. First shot wentBOOM, second shot went BOOM, third shot flash in the pan, BOOM on secondstrike of the cock. (The next 15 shots went BOOM

)
Here's the target - not bad for the first shots from a new gun by a guy who has never shot a flintlock before.
