Boom J. has an excellent idea here, Spuddy. We use a Safety Rammer every time we load our cannons. The photo below shows a type anybody can make very easily and costs only about $8.00 for the parts at your local Home Depot or Lowes. There are only two fine points in making one of these "Finger Savers".
One, make sure that the dowel you hang on to is 1.5 or 2 times as long as the dowel that rams the charge and then the shot.
Two, taper the end of the long dowel for one foot, (zero to 1/8" deep all around) where your "gloved" hand grasps it, (align with two hands; ram with one). Also, the copper plumbing elbows and straight piece DO NOT have to be soldered; 5 minute epoxy can be used in this construction, metal to metal and wood to metal. A fancier one can be made at some future time. This one can be made and in use in two hours. This design keeps your hands
behind the muzzle at all times during loading.
FYI,
Mike and Tracy
Tracy uses the Safety Rammer during loading of "Ugly", our first accurate rifled cannon tube, (5 shot, 3.25" group at 100 yards).
