Recently acquired a cast iron cannon, English swivel, that is the diameter to shoot golf balls. Does anyone know a good powder charge to start with and what might be considered the max charge. It is one of the Hern Ironworks Cannons.

Mine are steel, so I can crank on it a little. 250Gr FFFG is about right, double that for a blank.

According to industry standards 1.5-2" diameter and 25-50" barrel length is 656-875 grains of black powder. HOWEVER: My personal opinion is that is way to much powder! Start with about 500 gr. and work up if necessary. Don't blow the gun up!

Please see the comments by the moderators about such 'cannons'. I don't believe it's OK to discuss such items. Thanks.
