I have just traded for a 32 cal percussion muzzle loader. I don't know what size RB'S, to shoot in it and what powder charge? I have been shooting OO- BUCK SHOT in it. I use 30 grains of 3FG. with a felt wad over the powder and one over the RB. and it does crack when fired! it is marked GOUCHER on the lock with a hunting dog behind the hammer. it is odd that it has no half cock on it. I removed the lock and it never had one, odd? I have never seen one without a half cock, any one else? it is a half stock, octagon with all brass furniture. and has a cupped brass ram rod, that has a slotted bottom for attaching a patch to it. so just what do I have, any one know? all help would be appreaciated.
