  A while ago we had a thread about high-speed photography and such. I think my friend and I took some curious pictures today, not sure how interesting they will be, but it was enlightening to learn what a DSLR could do in this kind of situation.

The camera in question is an Olympus E-510 with a Zuiko 14-58 F2.8 lens, a little dated and nothing special to begin with. In the midday sun, we were able to get a fast enough shutter to be able to capture bullets. Because of how these kinds of shutters function, the bullets are still quite blurry and faint but they're still visible.

Video is related to explain how the shutters typically work, to explain why the bullets weren't exactly as crisp as one would expect from shutter speeds of 1/4000th of a second, and why they're blurry in a slightly asymmetrical way due to a "rolling shutter" effect.

Also these guys shooting a giggle-switched AR-15 was adorable, great footage as well.

It's a 7.5" AR with a muzzle brake I made. It mounts over an A2 flash hider, has a bunch of small ports on the sides, and in dim confined spaces looks like pic related.

Good shooting and it's really cool to see it in slow motion. I have some chinese 7.62x54R that I've felt hang-fired by less than a tenth of a second, I should try shooting it while filming with my potato camera to see if it was my imagination.

At least it comes with nifty brass clips.

To be fair these are rare in the worst of cases and really only happen with dubious ammo. I think it would be best to immediately clear a malfunction normally and if you're using ammo that could be weird, make a note to let the malfunction sit for a second as an exception.

Doooood. Way to go with ALL the auto-revolvers. So it looks like they Webley has a shitton of muzzle flip.

Do you think there's any merit to the idea? Or is there just no point in a world of semi-autos?

thx bois

Honestly, I have a lot to learn when it comes to recoil management. Despite this, I feel that it's very soft shooting and the trigger is incredibly light and crisp. The most fun I have is handing either of them to people and watching them get confused trying to recock the hammer after the first shot.

I think they're wonderful and novel designs especially if you're already used to using speedloaders, but yeah, they're definitely outclassed by autoloading pistols in current year and would probably be really expensive to produce. That said, I heard Mateba is starting production of the 6 Unicas again and have secured an importer in the US though I don't know who the importer is.

Really like the looks of the Mateba 6 Unica auto-revolver, but the prices for these have been all over the place. Heard of ones for $1000 to one being sold now on GunBroker for $6300. This unusual one with a 6.75" .44 Magnum barrel and plastic and checkered wooden grips sold for $5463.

Another unusual auto-revolver is the Norwegian Landstad
The Landstad revolver was an automatic revolver of Norwegian origin. The weapon had an unusual feeding device that used both a 2 round cylinder and a grip inserted magazine.
It was chambered for the 7.5mm Nagant cartridge, which at the time of the creation of the Landstad was also used in the Swedish Mod. 1887 and Norwegian Mod. 1893 Nagant revolvers.
The revolver design was patented in 1899 by Halvard Landstad, from Kristiana (now known as Oslo). Landstad designed the revolver with his own money and presented it to military trials in 1901. The gun never went into production because the revolver failed in the trials, but the inventor kept a prototype of the gun. It was donated to the British NRA after the inventor's death in 1955. In 1977 the revolver was sold in an auction.

Landstad 1900 Automatic Revolver https://www.forgottenweapons.com/landstad-1900-automatic-revolver/
We spent a bunch of time earlier this week covering the Webley-Fosbery “automatic revolver”, and I would like to close out the week with another pistol of that type, but one that’s even weirder than the Fosbery. I don’t have much information on this piece, but did find some surprisingly good photos that were originally in a Norwegian magazine. Pretty much everything I know about it comes from the captions in the pictures, which you’ll see if you read Norwegian or translate them.

Anyway, this is a design patented in 1899 by a fellow named Halvard Landstad, who lived in Kristiana (now called Oslo) at the time. He designed the gun on his own dime, and presented it to military trials in 1901, which it failed miserably.

What makes this design really unusual is that it uses both a revolving cylinder and a box magazine (a bit like a Dardick, actually). The magazine – which doubled as the left grip panel – held six rounds of 7.5mm Nagant ammunition (a common caliber in that time and place). The top rear of the action contains a slide that comes back with each shot:

File 155744560898.jpg - (38.93KB , 462x324 , pistol Norwegian Landstad cylinder mid-rotation 1.jpg )
More unusually, the cylinder was actually flat, with only two chambers:

Pic - Landstad cylinder mid-rotation. Note how it is flat, with only two chambers.

The firing cycle went like this: a round from the magazine would be loaded into the bottom chamber of the cylinder. Pulling the trigger would rotate the cylinder (like a DA revolver), moving the round up to the top, in line with the barrel. The hammer would fall, fire the round, and the recoil energy would cycle the slide assembly at the top rear, extracting and ejecting the empty case.

I’m unsure on a few points, like whether it could be fired single-action as well, and how the mechanism controlled loading of cartridges from the mag into the cylinder. Here are some photos of the Landstad disassembled:

File 155744571767.jpg - (105.90KB , 905x591 , pistol Norwegian Landstad auto-revolver 1900 in 7_.jpg )
The gun never went into production, because of its dismal performance in trials. But it appears that the inventor kept the prototype gun, and brought it with him when he emigrated to the UK, living in Middlesex until his death in 1955. It was donated to the British NRA and kept in their museum at Bisley until 1977, when it was sold at auction.

The Landstad 1900 differs fundamentally from the more commonly known auto-revolvers like the Webley-Fosbery and Mateba in that it actually ejects cases when empty. The other guns are more accurately described as “self-cocking revolvers”, since they must be loaded and unloaded just like typical revolvers. Not a tremendously important distinction, but a valid one all the same.

Landstad 1900 Autorevolver Disassembly: You may recall seeing my post about the Landstad model 1900 semiauto revolver a while back…
Well, the gun (only one was ever made) was in a British collections for a hundred years, but recently was purchased by a Norwegian collector, and has now returned to its homeland. Thanks to Lars, a reader who happens to be a Norwegian gunsmith, we have a series of photos showing disassembly of this unique firearm. Thanks, Lars! https://www.forgottenweapons.com/landstad-1900-autorevolver-disassembly/

Eon: The Landstad loading system from magazine to “cylinder” closely resembles the British Needham rifle patent, circa 1868. (Not to be confused with the Needham conversion breechloader Ian covered here a while back.)
It fed its “two-chambered” cylinder from a Winchester-type tubular magazine under the barrel, was worked by a lever-action similar to a Bullard, and used cartridges very like the Colt Thuer conversion revolvers, which were fed in from the front and ejected out the front as well.
The Landstad reverses this procedure, because obviously there’s no room for a tubular magazine out front due to the gas piston assembly, and the rimmed Nagant revolver round had to be fed from the rear anyway.
There were also four-shot “Bar” pistols, manually operated, with double over-under barrels that had a cylinder setup like this. Most of them were in .22, .25 ACP, or even .32.
All of which goes back to the old saying, “In engineering, if nobody does it ‘that way’, there’s usually a very good reason.”
