ok so YEARS ago one of dads buddies gave him a percussion sidelock handgun...guessing it to be 45cal maybe? but have to measure it..i know its a few shades bigger than a 40..(40 cal bullet fits no trouble..) its one of those full stock style guns...


only markings i can find is "SPAIN" on the underside of the barrel and on the inside of the lock plate...

it looks like it has been fired...but i dont know for sure....


i thought it would be fun to load up and shoot it at camp and stuff with the buddies when were all shooting our flinters and what not....

but have no idea what to stuff it with? anyone know anything about it? what i can safely load it with powder wise? was just going to buy [censored], patches and caps..got 2, 3 and 4fg available..i know spainish made muzzleloaders arent the best...i dont need a super powerful load or anything....just something we can shoot cans with or whatever....

anyone have any knowledge?? not trying to blow myself up....but at the same time ive been wanting to shoot it since i got it and never have...

thanx

Assuming it is a 45, from your description , you could shoot either 2fg or 3fg. I would stick to about 25 grains. As for the size of roundball etc., there were 41's, tight 44 calibers probably actually 43, standard 44's, 45's and 50's. Spanish guns have been imported for almost 50 years and it could be almost any of those. Some of the difference can be taken up by patch thickness, but you are still going to need to measure the bore and subtract about 10 or 15 thousandths to get the roundball size needed. Do you have access to a vernier caliper? Even the fiberglass ones used by reloaders to measure case dimensions. Getting more accurate than a hundredth is probably critical. The rim diameter of a 357 Mag is .440 Try the base of the 357 in the muzzle. If it has just slight play it is a 44 or 45. If it doesn't fit it is something less than .44 (incidentally, an empty 357 case would make a good powder measure for the gun.

I f you have a 30-30 case, the diameter of the rim is .506 so it won't fall down the bore. Flip the 30-30 case around and slip the case in as far as it will go. The body of the case just above the rim is .422 ,, so if the case doesn't slip all the way to the rim, it is probably a 41 caliber.

So there, you have a way to measure the bore, without a fancy vernier.

If it is one of the old 41 caliber guns, you will need 40 roundballs and about .015 patches, if a 44 caliber, I think Hornady sells .427 roundballs and the same size patches. If it is a 45 caliber, 440 roundballs and the same patches.
