It is important to mention Drop Towers from which known drip sizes of lead were released to fall and land in water to cool, it was the easiest way to mass-produce relatively accurately sized balls that could then be press-forged into bullet slugs. This is why the bores were in weights.

[@everettputerbaugh3996]

Not to mention that it simplified the description of a shotgun bore (of which only the .410 is described in inches).

Gyro Jet and .45 acp are low power. You should be disappointed.

[@backcountry164]

The 44 magnum was the most power handgun in the world when Dirty Harry was filmed. The 454 casul was still a wildcat cartridge at this point, so it isn't considered.

[@MichaelScheele]

Correct, the first production firearm chambered in .454 Casull, the Freedom Arms Model 83, wasn't introduced until 1983. The cartridge itself was only standardized (SAAMI specifications) in 1997. When Dirty Harry was released in 1971, it was the most powerful PRODUCTION handgun in the world. There are always wildcat cartridges and custom firearms out there that will be "overpowered" compared to readily available production firearms.

[@thelordofcringe]

454 was only even possible to shoot from old colt SAA's that had to have almost every part of the frame case hardened in order to not shatter when fired. Despite this intensive process, the. 454 casul was actually quite popular in the enthusiast community, which is why such an obscure and niche round got itself a dedicated production gun in the 1980s of all times. There was even law enforcement interest from random cops but it seems unlikely any ever carried the 454 when it was still a wildcat cartridge, as the potential for their gun exploding likely meant no cop was ever getting that approved.

[@magnemoe1]

I say this sounds likely,

[@roblopez8481]

The AF2011 has 2 triggers, they're probably no longer imported to the US because it's an expensive pain in the ass to import firearms, the manufacturer has to prove the firearm serves some type of sporting purpose like hunting or target shooting.

[@chrism6880]

​@roblopez8481 as stated in the video, the triggers are mechanically linked. Pulling either fires both chambers, and the firearm is incapable of cycling from a single cartridge.

[@roblopez8481]

@@chrism6880 I've seen other videos on it, some explained it gets around the machine gun classification cause it's considered volley fire. There's a 22 magnum double barrel revolver with a single trigger that has two finger grooves that's legally sold because it's a volley firing gun

[@addicted2monster88]

No. You can buy it still today in the U.S. you just have to get one imported or buy one already here. It's a Hassel and will cost. And it has to be done through a dealer. Anyone wanting one, willing to pay for it, will know how to get one. APF has one listed for 9k. But there will be other fees on that. Not really a gun most people are going to pay for.

If the sear isn't being tripped once locked into battery and the hammer/striker is following it home you will probably have FTF from light strikes or worst case scenario and out of battery detonation.

Fanning a SA revolver means gripping the revolver with only one hand. This would be a profoundly bad idea unless you are built like Scott from Kentucky Ballistics. Even then, it would not be controllable enough to provide any noticeable increase in the rate of fire.

Holland and Holland and Parker used to make "Howdah" guns, which were mostly 20 gauge or less as backup guns for tiger hunters. They would be in their howdahs, the little huts or platforms on top of an elephant used for safari, shooting down on the tigers beaten out of the bush. If they missed, the tiger might climb up to get them, so they needed a backup gun. Howdah guns were loaded with blackpowder and roundballs, designed for pointblank range at an angry tiger. When cartridge guns came around, they made them in the various "smaller bore" rifle rounds in single and double bore, pistol versions of their shotguns or big game rifles.

[@wittsullivan8130]

A few years ago at SHOT Show, Taurus brought a 28 gauge revolver version of the Judge to the showroom floor for a half hour before the US BATF (Bureau of Alchohol, Tobacco, and Firearms, aka, the Fun Police) had questions. Handguns over .50" in bore diameter can't be imported without their consent and Taurus forgot to ask, so they had to take the 28 gauge revolver (.55" bore diameter) off display. It had a rifled barrel to avoid being a Short Barreled Shotgun or Any Other Weapon(AOW) requiring extra paperwork and taxes for potential buyers, but it was still considered a Destructive Device as an import from Brazil. If it was made in the US, it could apply for a sporting exemption like the .600 Nitro Express single shot from Thompson Center and a few other larger than .50 caliber pistols. They were able to import it and sell it as a 28 gauge revolving shotgun with the proper length smoothbore barrel and overall length, but 28 gauge is not common in the US.

My guess is that they can’t import the double barrel 1911 because I think it technically violates the NFA as a machine gun. The NFA defines machine guns as basically a single trigger pull firing more than one round. So while this is obviously not a machine gun, it kind of is by definition. 16:42

I recall an episode of the 60s spy comedy Get Smart in which Maxwell Smart and 99 wanted to stop Kaos from smuggling Stereophonic Pistols into the U.S.. These pistols were 2 6-shot revolvers mashed together to create a 12-shooter. Obviously, if Kaos agents carried 12-shooters, Control agents with 6-shooters would be at a big disadvantage in gun fights. At the end of the episode a Kaos agent grabbed one of the stereophonic pistols to shoot Max only to discover that the Japanese manufacturers had taken "stereophonic" literally and made gun shaped radios. The double M 1911 reminded me of the double revolvers.

[@squizzlor]

There was also a arma light style riffle that also did the same. Though these both are not the first of this type of fire arm produced. These were both produced for the civilian market as a curio. As a double barrel riffle was tested for the same project that the AN94 was entered into. Placing more bullets into the same area was considered for armor penetration, when modern metal and ceramic plate armor was first created.

05:00 Because the .454Casull fires the same diameter bullets as the venerable .45ACP war veteran, it is still the largest legal caliber sports gun in most of Europe, and therefore can be obtained legally despite its 1.5x .44Magnum power envelope. My first experience with my brand new 454 Ruger was the range master tapping me out with a few napkins. The recoil had torn the skin between my thumb and index finger so I was dripping blood like a stuck pig. The recoil had also numbed my hand so much that I hadn't noticed.

Sir Samuel Baker used a very large bore muzzle loading rifle as a rifle of last resort when pursuing elephants in very heavy cover during the mid 1800's. Technically it wasn't a 2 bore, but it did fire a half-pound bullet with 270 grains of black powder. It weighed about 20 pounds, and Sir Samuel dreaded firing it, the recoil was so severe. The rifle was built by Holland & Holland, and they still have the records of its manufacture.

Good vid. Wh40k fan and ive always loved the gyrojet but ive always thought it made more sense as an indirect fire weapon. There was a tank called the Sheridan, in the 70s I believe, that had a gun launched rocket as its main weapon. Weapon had mixed results so it was abandoned. I bring it up because although it was never made small it is the lore accurate bolter. A gunpowder charge launches a rocket which performs better than a shell or slug. Maybe the sheridan could be a future video?
