"The Cannon Diet", yep, wooden balls for my 2.25" bore Howitizer. Kinda light, but lots cheaper than lead! ("Red Bull" can...just right!) Looking for them for the Mortar, 3" wooden...humm, wonder if a croquet set would be the right size? Tennis ball too small, baseball too expensive, softball too big, ..."Hunts" Tomato Sauce, 15oz...Just right! (Diet, of course!) BoomLover
