The Pocket Cannon – A Legit Mini Cannon

This one falls into two simultaneous and often contradicting categories of “Why?” and “Why Not.” Introduced by Mini Artillery, the Pocket Cannon is a legitimate cannon. Loads from the muzzle, using real powder, and shoots real .30 cal cannon balls.

You can purchase a cannon for $39, which includes the “ramrod” and 3 steel balls as a starter kit. The Mini Cannon uses standard black powder and slingshot balls.

No figures on velocity, accuracy, or powder. Regardless, these can put a real eye out so be responsible when having fun.

    I’d be worried about using steel shot. That stuff has a tendency to ricochet badly. Even in slingshots and BB guns it’s a problem. Lead is safer, it has a tendency to deform instead of bounce.

    I wonder if 32 cal (0.311 in) lead pistol balls will fit?

      Well, its USD 40, so its not like you’d be out a ton of cash if it didnt. Although i might recommend standing back the first time.

        I was looking up .30 Lead Balls in google and found out that No. 1 size buckshot it 0.300. So buying a bag of that should work (and it’s cheaper than steel slingshot ammo, at least before shipping).

          I bet that Lee Precision (reloading company) would have a round ball mold available for that caliber- they have a really large selection.

      a back-up, back-up weapon…..

  • Paul White

    It’s so cute I want one regardless of how silly/stupid it is.

    • nova3930

      I’ve got several. They’re silly/stupid fun 😀

      • Jeff Smith

        How loud are they relative to, say, a .22lr out of a rifle?

        • nova3930

          The ones I have are little more than air rifle level. More of a poof than a bang

    Not going to lie just impulse bought this

    I need one of these.

  • flyingburgers

    The picture made wonder if I could put one together out of pieces from Thorlabs.

  • jamezb

    That video is a classic.

  • jamezb

    It should come with a QD clamp base for rail system attachment …

  • Bob

    How ’bout one with a Sig brace ?

    If you search “mini cannon”, you’ll find out that there are a whole bunch of these. I was first turned on to their existence by tnoutdoors9’s video from a year ago:

    • Boris

      1/4 scale of Zis-3, 76mm so 3/4″ cannon laughs at puny 45cal ; )

  • Cymond

    I had a weird childhood. My dad got me a 45 caliber mini cannon when I was about 10, but it was bronze and about 6 inches long. It was a heck of a lot of fun, especially for new year’s eve.

    I’d love to get a mini cannon again, but I want one that isn’t thrown across the room by its own recoil. Sadly, they’re a bit expensive and I can’t justify something so frivolous.

  • anon

    But can it take glock mags?

  • jeff k

    i thought this was dumb until i watched the video . .now i want one lol i can finally put my kids bag of old army soldiers to good use

  • G0rdon_Fr33man

    Friend of mine has a full-size one he made himself out of hardened steel. He dimensioned it properly with help from an old weapon-designer so it could withstand the pressure of firing a 1 kg lead ball with black powder. The thing is insane (and is casually parked in his driveway). He is not allowed to fire it as he pleases (it is in a neighbourhood ), but have to apply to the Police for special events. Anyway, we once took it to the range and fired ball-bearings to a tree… Massive damage! Damn I want one for myself.

  • Zebra Dun

    Look out Fire ant mounds!

  • Ratcraft

    I made one like this, but about 6 inches long, at work 10 or so years ago. It sits on my desk at home.

  • Cannon? Looks more like a mortar than a cannon.

  • David Sharpe

    I’d rather a .177 BB cannon. Anyone know where to find those in Canada?

  • RealitiCzech

    I want an 1897 French 75 scaled down to take centerfire pistol calibers. I don’t know why, but I could figure out a reason.

  • Jeff Heeszel

    Nothing like shooting a bunch a little cannons on in your house and at your light fixtures. priceless!
