Does the chrony say 580 odd metres per second.

Feet per second Scribe. Barrel is pretty short.....shoulda been longer but

so 19.05 / 40 = .476 + 19.05 = 19.52 for a 3/4 bore? and we would need an inch an a half past the bottom of the hole in laymans terms. 31.8mm at our narrowest point would give us our safety factor of 1.5 bore....

Sorry for the ramblings but am I on the right track?

Who casts 3/4 balls or.... how round do they have to be with a homemade mould??

Thanks

Brown Bess is .75 cal so .75 round ball will be easy to find, or a mould,

Bean

With a 40mm OD bar you could bore it big enough to shoot a standard 69calibre ball i.e. 69cal ball = 0.675"

Bore dia would then be 0.692"

Moulds for 69 cal are easy to get too.

You could also shoot 730gr Minie balls too. :shock:

Drill the fuse hole 1/8" and on a 10 degree angle into the powder chamber.

Cheers

Sourcing some 7/8 carbon balls, it's 34 at the narrowest point and will proof in a covered hole I think
