I purchased two open flintlock pistols at auction. One from 10-ring precision is .45 caliber and says to use patched .440 round ball, no problem with that one. The second one has absolutely no markings anywhere. Has a false muzzle, as best I can measure at the lands it's .375. The false muzzle just before the rifling is. 390. I'm pretty sure it would be. 36 Caliber. So what size ball? Patched or unpatched? Open to your wisdom.
