    I used scotchbrite, steel wool, sandpaper, WD40, drill, & reciprocating saw to smooth out the bore of a cannon but its still got some more work to be done. My biggest issue is the "lumps". Any recommendations?

    Really? Nobody?? What if it were fired a few times? Would that help?

    Dude! Some of us work for a living- away from a computer!

    Did not say what caliber the bore is- try a cylinder hone on a drill motor. The other stuff will polish, but will not take off the high spots.

    one guy I met at a range, was 'cleaning out' an old rust bucket by shooting it!!

    He had done all the scrubbing, but was still intent on getting more of the junk out. He was lubing his patches with ?topal? tooth paste.. Some kind of slightly abrasive tooth paste used for smokers to whiten their teeth.. ( what he told me it was used for ;) )

    anyway, he figured the light abrasive.. would scrub out the bore as it shot? Never saw him again to confirm, whether or not it worked? Later on a read through all the articles about 'Fire lapping" bores.. Same basic idea, harsher compunds is all..

    For what it's worth?

    It is against federal law to fire a projectile from a cannon. It will be classified as a destructive device. They do not fall under blackpowder and musket guidelines.

    Keep this in mind.

    I do not believe this to be accurate. But I'm just a farm boy.

    I know the headmaster at my high school had two that he fired regularly (including on some civil war movie), but he may have had a license of some kind.

    I don't remember anybody ever rolling his yard.

    Ignorance is not a valid excuse. Educate yourselves gentlemen. Unless you would enjoy a visit from the alphabet agencies and a free vacation.

    Willfully,

    Please correct me if I am wrong! But with the civil war reenactment groups around the country who fire cannons. The difference in the requirement of a license for a destructive device could be that they only shoot powder charges with out any projectiles? However it does require a lot of powder charge to get the effect! Not sure of the legal requirements for this but that would seem to be the case since there never seems to be an issue with this activity during the reenactments? Unless the owner of the canon has a license?
    Some one can fill me in also on this issue! Since there are a lot of us here on the FTF to learn ourselves!

    Folks- this is covered in the 1934 National Firearms Act. You can find it in 26 US Code, Section 53.

    In a nutshell- a muzzle loading cannon is NOT a destructive device. It CAN fire shot. It cannot legally fire shell. Shot is a solid projectile. Shell is a hollow projectile with a bursting charge. THAT projectile is a destructive device, the muzzle loading cannon is not.

    A 75mm howitzer IS a destructive device- breech loader, larger than 1/2 inch bore, no sporting purpose. A 6 pounder Napoleon smoothbore, muzzleloading cannon is not- uses loose powder and ball. A Civil War vintage Parrot rifled cannon is not a DD- muzzle loader. HOWEVER- the Parrot Gun fired an explosive shell. The shell IS a DD.

    A number of folks legally build and shoot bowling ball mortars, using a welding size oxygen tank as the tube. These are muzzle loaders, and can lob a bowling ball damned near a mile. Not a DD. If that were an explosive filled shell instead of a bowling ball, that would be different matter.

    OK, I knew that. I was just foolin' around. I have a couple cannons and shoot often. I have made several for friends also. But hey, I am just a farm boy.

    Thanks, y'all for the good info. I'll order a cylinder hone soon. I'll also get some abrasives.

    It's only illegal to build and fire breech loading cannons. Some of the guys around here have been building cannons that shoot golf balls.

    How about the annual cannon target match -- I think NSSA does one but that's not the one I'm thinking of....

    So your barrel is open on both ends? Take it down to someone that has a bead blaster, and blow beads through it for a couple minutes, that will remove all the crud and polish the inside slick. I do that on old cruddy shot gun barrels to clean them up.

    Rifling?

    What sort of beads? I would go with one of the aggressive bore cleaning pastes before resorting to bead blasting. Used with a brush no part of the grooves would be missed.
