Looking for a bit of advice from any BP cannon guys out there.....I'm new to B/P scale cannons but have acquired a few which I'll get proofed eventually and use on the local range. The latest is an 8 bore naval cannon, approx .840" smooth bore, solid cast 13" bronze barrel and already proofed for 80 grains of BP and an 860 grain ball so I need to get a ball mould made up. The thing is I'm not sure if the ball should be patched or not, if so I need to take this into consideration when I order the mould. Can anyone give some advice on this please ? Maybe I should just do the same as if it were a musket being fired although I've never owned a musket.
