Just got home from a morning of blackpowder pistol shooting at the club, so I've sent your video to a few of the members who I shot with today.
We only use 20grs of BP and 20grs of filler (polenta etc) in our .44-40's for the sake of being more competitive (accurate) for the 60 shot match, its also more
pleasant on your wrist. It was only 4° Celsius this morning and very still, we could hardly see the targets at 50 metres there was that much smoke.
That mortar is awesome and thanks for the photos and the video.
Brilliant Daniel....literally....what a blast!
