The New Russian Shotgun Round .366 TKM for SKS, AK Rifles

11873619

Russian ammo maker Techkrim (small company specializing mostly in less-lethal and sporting ammunition) has introduced a new shotgun round, called the .366 TKM

It is based on the 7.62×39 M43 case necked out to .366 (9.5mm), with taper but no neck. Its main intent is for the use of surplus 7.62×39 weapons bored out or rebarreled to smoothbore configuration, preferably with Paradox rifling at the front 140mm (4.5″) of the bore.

Due to Russian gun laws, a rifle license can be obtained only after a minimum of 5 years of shotgun ownership. However, many people here want to own “military style” weapons for plinking, sport shooting, home defense and hunting, without that idiotic 5-year waiting period.

This ammunition, combined with rebarreled SKS carbines, offer a close match to a rifle at the ranges of up to 100-150 meters, with the same look and feel as the original Simonov. Apparently, other 7.62×39 weapons such as AKM also can be easily converted to smoothbore .366 configuration, but at this time only the Molot VPO-208 (rebarreled SKS) weapons are introduced along with this new ammo

Basic stats are as follows:
Case dimensions, metric: 9.55x37mm
Available projectiles:
11 gram FMJ slug at 700 m/s (170 grain @ 2295 fps)
13.5 gram polymer-coated lead slug at 640 m/s (208 grain @ 2100 fps )
15 gram FMJ and JSP slugs at 620 m/s (231 grain @ 2030 fps)
20 gram birdshot (0.7 oz)

    Rimless shotgun ammo, excellent. Like a cross between a carbine and a shotgun. And the bullet weights and muzzle velocities, like an improved version of the .351 WSL.

    How are the bird shots held together? I don’t see a plastic capsule. Are they glued?

          It is an annoying ad if you’re on mobile.

            Aha.

            thanks!

        Meth makes people skinny genius. Thanks for insulting my sister none the less. I fixed the problem.

    Russia seems to do the concept of high performance small bore slugs very well. I’ve certainly read before that Barnaul .410 slugs shoot very accurately out of the AK derivatives in that cartridge but these are a really interesting idea. Although they seem largely about having a rifle that isn’t a rifle it’d be extremely interesting to know how effective people find them. I suspect that these would be very useful.

  • Giolli Joker

    Waiting to see the concept applied to 50Beowulf/458SOCOM, for 20gauge-ish performance in an AR-15 upper…
    Not that I can think of any use of it, just because it sounds cool.

  • iksnilol

    Seems to be a bit weaker than 20 gauge. Lighter weight, similar/same velocity.

    I’d say the tradeoff is worth it considering you can have double and quad stack mags made for it.

    • Kovacs Jeno

      Imagine the shotshell round from a full auto short barrelled AK for SWAT!

      • iksnilol

        I’d call that a bad day.

  • MPWS

    This may have military application. Five inch drop and over 2k J at 100m is not bad. Just wonder how much it would be at 200m, which is most encountered combat range. Next question: how would it fly out of rifled (or perhaps partially – as author suggests) barrel. As we know, many inventions of past came as a result of coincidence.

    • Bal256

      Military application? No. Thats dumb. A round design as a workaround to civilian regulations does not make good military issue weapons. Replacing rifles with low caliber shotguns is idiotic.

      • Esh325

        Maybe not this exact round, but the idea of adapting shotgun rounds to commonly used rimless rifle designs is a novel idea.

      • Bill

        I wouldn’t have been quite that blunt, and while shotguns have a lot of applications in law enforcement, and some applications in the military, I don’t think this is a contender. And if you are just going to use the slug loads, I’d recommend that your first shot be at someone with a rifle that you could then take.

    • gunsandrockets

      Project salvo load, three to four 000 buckshot pellets with dispersion controlled by paradox rifling.

  • Paul Epstein

    Honestly, the SKS version strikes me as almost a post apocalyptic survivalist weapon- single load shot shells for hunting small game as you find it, keep the magazine full of slugs for larger critters. Ammunition easily remanufactured from existing stockpiles, or even new brass. Other than the barrel, uses SKS parts, so easy enough to keep some replacement parts on hand or trade for them after things settle down a bit.

    So, I guess what I’m saying is, it’s a range toy.

    • TJbrena

      Fury Road had a neat SKS. Wasn’t stock, but wasn’t too tacticool either. Even the Glock was worn enough that it looked at home in that movie.

      • Tassiebush

        Hopefully these ones are made all shiny and chrome

          • Tassiebush

            What a lovely day!

  • Kovacs Jeno

    A ten-shot low recoil compact cca. 20-ga shotgun for home defence, not bad. The Russian gun market is one of the most interesting. Their illogical regulations gave birth to several innovations.

    • The genesis of creativity and innovation is often restriction.

  • Mr. Moo

    This ammunition exist, just because people in Russia need to handle shotgun for 5 years in order to have ability to buy rifle. So this is the way to sell more SKS and AKM reberreled with shotgun barrels

    • Esh325

      It’s a great idea.

  • Anonymoose

    No buckshot though?

  • gunsandrockets

    Hmm… like a smokeless powder rimless cased .410 shotgun that feeds from existing 7.62x39mm magazines. Sounds like a winner.

    Imagine a 000 buckshot loading.

  • Southpaw89

    Clever solution to an idiotic problem, I have no idea what sort of logic was used to create that law in the first place. Still, the round interests me, it could make a good short range varmint round, and I cant help but wonder if these shotguns could get trough our own idiotic import laws, then all you would need is a rebarrel to have a nice little carbine on your hands.

    • Esh325

      Go to Russia and most Russians would say the same about your laws.

      • marathag

        what, show a Picture ID, answer some Qs on a form, wait for a phonecall to finish, fork over some cash, and take home a Barrett 50cal?

        yeah, think that was just insane.

        Insanely good, that is.

  • Tassiebush

    It depends of course on things like patterning and slug accuracy but this would be pretty cool round for applications other than retrofitting SKS or AK. I could definitely see a lightweight folding shotgun or a small double or rimfire combination gun being really cool in this load. Even a bolt action carbine platform like the cz527 or similar would be great. Firing a .7oz load from such a small package is quite an impressive achievement too. I’d definitely like to see this catch on outside of Russia if it performs OK.
