The quest for high-capactity firearms [ Part 2 ]

After writing the The quest for high-capactity firearms post, readers told me about other interesting attempts at high capacity guns.

Porter Revolving Turret Rifle

9-shot; .48 caliber. In excellent overall condition. Bore is excellent plus; 28″ barrel. Metal is smooth and well marked. Showing little or no use. Manufactured in 1851. Mechanically excellent. Wood is excellent, with one tiny area of wood loss. Only 1250 Porter Turret Rifles made, in three types, of which approximately 375 were type II. Lacks rear sight, cover screw broken, otherwise complete and excellent. A very advanced weapon for its time, and a competitor to the Colt Revolving Rifle, many were used during the Westward Migration. Seldom available on today’s market, this example is in far above average condition. $11400

If you are interested, this rifle can be purchased at

Isaiah Jennings 12 shot repeating flintlock rifle

According to the press release [PDF warning], when this gun was auctioned off, it achieved a record sales price in Louisiana.

An 1820 Prototype Isaiah Jennings 12 Shot Repeating Rifle, engraved with the serial number “No. 1,” generated a great deal of interest on the telephone, through eBay and from within the room. Bidding finally stopped (and the applause began) when a local purchased this exceptionally rare rifle for $34,000.00, making it a Louisiana record price for a firearm sold at auction.

Does anybody know how this type of gun works?

Ingrham’s Underhammer Harmonica Rifle

The Underhammer Society Blog has a post about a modern reproduction of this 175 year old rifle design. Be sure to watch the video.

The Puckle gun

This gun dates back to the early 1700s! It fired 32mm caliber projectiles at a rate of just under 10 rounds per minute. I think make almost makes it an Auto-Cannon 🙂

    Greetings from Texas,
    I'm playing catch-up here so bear with me. History Channel had a program on 'Bizzar Firearms' this afternoon that talked about the rifle with the two locks Matt Groom was talking about. They described it as working like a roman candle. The first trigger and lock lit off a number of shots (don't recall how many) and then the second barrel did the same thing. I guess make your peace with the lord and pull the trigger, hold on target until it stops 'erupting'! In that case single shots don't sound half bad.
    I would love to get my hands on a revolving rifle, or -shutter- try to build one. The big problem with it from my reading was, and I am quoting here "the weapon has a distressing tendency to set fire to the soldiers tunic sleves." I once saw an old jacket with a scorched leather patch sewed to the inside left sleve from elbow to wrist. I thought of Colt revolving rifles at once.
    Steve_the_Brit is right about the pucket gun firing two types of projectal. The squar shot was suppose to be more painful, the round shot was for civilized enemies - read christian. I don't think I want to get shot with either. It's in the online article but back before computers (I'm dating my self here) I read books on firearm history. Must confess I still do. All manor of interesting tidbits, plus books don't crash.

      @Arthur B. Burnett Arthur, yes, another problem was the blast igniting other chambers if loose blackpowder was floating around the mechanisms, which was a major problem with the Colt revolving rifle.

    Every two years, during the Orlando SHOT Show, Knight's has a tour night where they have live music, free booze, a catered dinner, and tours of Knight's Arms Museum and their Tank Museum. It's badass, and anyone who can get into the SHOT Show can go (they even have tour buses that drive to and from the event), but the expense of such an event is a clear indication as to why their products cost so damn much.

      @Matt Groom Matt, very cool.

      The big boys spend a fortune on marketing. One contract will easily pay for maybe decades of marketing. I remember reading military journals that I was giving and being amazed at what was being advertise: double page ad for C17's, full page ad for Apaches, smaller ads for various APCs, rifles, trucks and so on. How many countries are going to be able to purchase Apaches? How many counties can Boeing(?) get export licenses for to sell Apaches? Very few I guess but the small amount spent on advertising would be nothing compared to the sale of a single Apache.
