The CHECKMATE Shotgun Slug seems to DEFY Physics!

We have another strange design by Evan today. Made of "potmetal" which isn't a very strong alloy, we propel these to over 1500 fps using rifling, a rifled choke, and a smooth bore.
Big thank you to our Patreon supporters!

Couldn't find the "Tracker B" shotgun in any of my searches, best I came up with was the Panzer BP-12? I guess it's being marketed under several brand names like most guns from Turkey.

[@taofledermaus]

Intreresting slug from Evan, seems to work well enough, and love the bullpup semi auto shotgun. I am a bullpup fan and that thing looks very cool indeed.

[@mikeblair2594]

I've never been a bullpup fan, but I'm starting to come around. I like the Desertec and the FAMAS, but I've never liked the bullpup shotguns. This one might change my mind on that. I still enjoy building flintlock firearms though. Its a feeling when you're finished that you've built not only a useful tool, but you've built a useful tool that's also a piece of art that will last generations if taken care of. Since I'm on disability, my selling the flintlocks pays for my modern firearms. Its a win-win situation. Cause I'd never be able to afford the modern firearms otherwise.

[@WolfoftheWoodsTactical]

​@@mikeblair2594I'm in the UK so real firearms like the bullpup shotgun are out of reach to us. I enjoy firearms through TFM and OG's Danger Show and Airsoft. All the best with your flintlocks and happy pewpew

[@carsonhunt4642]

@@mikeblair2594 I think non bullpup fans are ppl that have never used one! You not only get the length of an sbr, but full power of full barrel, and the biggest factor of all is the weight distribution is 100x more comfortable with the weight further back, and able to rest on shoulder.

[@carsonhunt4642]

Oh also forgot to add, thoese Turkish bullpups are as low as $200 on sale! Mine runs flawlessly, is a blast to shoot.

[@mikeblair2594]

​@carsonhunt4642 didn't I say that I'm coming around to bullpups? If I was to get a bullpup it certainly wouldn't be a shotgun. I have a browning auto 5 made 4 months before the great war and its been handled with kid gloves for the last 109 years. I have a model 1917 Springfield (the American Enfield) in 30-06. I also have military type firearms ARs of the 15 and 10 persuasions. And my favorite modern pistol is a Beretta 92 that was made for the Italian police. She's much larger than the M9 and fits my hand perfectly. All that said, I hunt with my flintlock rifles and fowler. You have to learn to stalk your game. You have to know you games habits. You have the skill of a bow hunter, but the killing power of a firearm. I don't need a bullpup because my days of jumping out of an APC were over when I caught a round upside my head that went out the left side of my face taking most of the bone with it during desert storm. I don't need to play soldier. I just need to be left alone

[@suzukiegi5699]

My respect to the man who made those projectiles. I can't imagine the work that went into those to make them that consistently accurate by hand. I wonder what his thoughts were as he was designing and testing. I also wonder what his logic was for creating these for at the time or if it was just 'hey I tried a thing just because I could and it worked.' I've always enjoyed seeing what people can come up with in any walk of life. A like and a sub for this.

You should have a contest. Show a projectile and viewers need to guess the designer. Or guess the shooter.

I really don't see why bullpups haven't taken over the market. If you ever feel how secure and steady it feels in close to your body you'll be a believer. I understand triggers weren't as good in the first bullpups but my Kel-Tec feels great.

[@carsonhunt4642]

I literally just commented this to someone other comment lol. Feels like an sbr but full power barrel length, and the biggest factor everyone underestimates is the weight distribution. I can hold a bullpup for hours and not get tired. The weight further back on shoulder instead of forearms makes all the difference

I've never seen pot metal that nice I've been rebuilding old carburetors for 40 years none of them had that shiny and non-porous metal, maybe they all look like that when they are new but when they get old they degrade. My main professor at McPherson College auto restoration program talked about replacement carburetors that would sit on the Shelf for years and when they open the box all I had were shafts, butterflies, clips and brass jets and all the pot metal had just turned to dust.

[@blankslate5981]
