Back in the 60's, I watched Lee Juras struggle with his .44 auto mag. (We called it the auto jammer). There are several 'unseen' problems using your sort of combination. Recoil is the main one...not for the shooter, but rather the gun itself. The automags beat themselves to death. The .454 with full loads will definitely batter the gun considerably. The recoil spring would have to be very stout, which will require a 'good man' to manually pull back the slide for loading. The length of the round is not a terribly important factor, but it will come into play. The rimmed case will mean the chamber walls will need to be thicker than normal (adding weight). It's doable...but at great cost and frustration. You'd be better off getting married...less cost and less frustration.

The design I have in mind (and nowhere else yet) has a reciprocating barrel that will push on the slide/bolt carrier. The slide's inertia will carry it back, unlocking the bolt, ejecting the case, and picking up the next round. It's a little bit different from the automag. The barrel will have to displace more weight. The barrel will have the strongest return spring I can fit behind it. These two things mean that the slide return spring won't have to be as strong as it would have to be on an automag type design. At least that's the theory. As far as accelerated wear goes, that's the price you pay for a powerful cartridge. The reason I'm considering a recoil operated system is to improve the disadvantages of the desert eagle design. My design would be able to fire cast bullets, without having to worry about clogged gas ports. I could also provide lighter springs to allow the use of 45lc ammunition. That's the beauty of rimmed cartridges. Case length isn't critical. As for the weight issue, wouldn't you want a 454 casull to be heavy? I would. Those guys with redhawk Alaskans in that caliber must really like pain. As far as the strength to cock it, this would definitely be a big guy's gun. This would just be for me, and I'm a big guy. I don't plan on selling them. I don't think it would sell, at least not in that caliber. Cost will be materials and time. Time is in short supply, so it may take quite some time. I wouldn't make it until January of 2017 anyway, if you catch my drift.

I wonder how much actual recoil the 454 has. It has a lot of perceived recoil, I know. However, it's usually chambered in revolvers that are designed with the bore axis far above the hand, creating a lot of torque. A full power 44mag is torture in a blackhawk, bearable in a redhawk, but quite pleasant in a desert eagle, which, by the way, is not that heavy.

lol judge, that would be an awesome gun to have in real life. alucard's colt based auto loader is about 13.22lbs, so it definitely has to be heavy. With that ridiculous recoil on a non-ported chamber, you'll need to design something to release all that pressure. Your action sounds like that of a long-stroke of a AK, but to be able to actually push a heavy slider back while keeping the design is to implement a flat passageway at the side paralleled to the barrel that leads to a chamber at the back and have the air expand it. Make it vented to avoid excess pressure. You'll probably want it made with titanium carbide lol Last edited by scoutzknivez; 03-02-2013 at 02:14 AM. |

The AK47 is a long stroke gas piston system. My design is recoil operated. I have no intention of making it look like the gun from the show. Even if I did, it wouldn't weigh that much. Ported chamber? The barrel can handle the pressure. The safety concern is to keep the gun in battery long enough for the pressure to drop to a safe level. The recoil operated turnbolt would accomplish that. Venting gasses out the side of the gun at the chamber would not only seriously decrease your muzzle velocity, thereby defeating the purpose of the big cartridge, but it would mean that, each time the gun is fired, a high-pressure jet of scalding hot gasses would shoot out of the side of the gun, and your brass,would have a hole in it. You need to go to the person that told you about "ported Chambers" and punch them in the forehead for me. There is not now, nor has there ever been a such thing.

The LAR Grizzly could be modified to take the .454. One would have to modify the magazines of the .44 mag. model to accept the Casull cartridges. J. Huntington has modified one of my MK I Grizzlies to take .475 Wildey cartridges and said the hardest part was the magazine work. He found some one to do the micro-welding necessary to modify the mags with out destroying them. |

There are a couple of stumbling blocks. One is that the Casull...having such a large capacity case...will require a slow burning powder to achieve its potential as well as a fairly long barrel...something on the order of 7.5-8 inches. Slow powders don't generally do well with typical locked breech operation. That would necessitate a rotating bolt and gas operation. Two...In short, the thing would be massive and not very practical to tote around. Not sure if the cool factor and "First Kid on the Block" to have one would be worth the effort and expense. |

The pistol was close to being a reality. I then lost contact with the machinist. I hope he's alright. The final design comes in at roughly the same weight as a desert eagle. I didn't design it as a CCW. I.designed it as a backup (or primary) for hunting things that can eat you. It will have a rotating bolt and a reciprocating barrel. I went with this for a few reasons. One was reliability. Gas ports can clog. Two, simplicity. Less crap to maintain and less to mess up. Three, compatibility with a wide range of loads. Gas operated pistols work with a narrow range of loads. The desert eagle .44 is a prime example. It requires very hot loads to function reliably. The only way around this is an adjustable gas system (a la wldey. Didn't work so well).Also, too slow a powder can cause problems. Garand shooters know what I'm talking about. Four, compatibility with cast bullets. Everybody knows that cast bullets in gas pistols is a no no. Five, ability to use 45 lc. Swap out a spring, you're good to go. There's no way to do this in a gas gun. Even if you could, most LC ammunition is loaded with a cast bullet. |

Just my 2% of a buck... If you can get ti to fly...IF...you can, it'll be expensive if you intend to market it. It'll also have a very limited market/narrow niche. I don't think it'll fly at the same weight/mass as the Desert Eagle, but I could be wrong. The cost of the pistol in such a small market...for a "What If/Just in Case" solution...when there are several DA and SA revolvers available chambered for the Casull...could scuttle it from Jump Street. If you just want to make one for yourself, that's a different matter, of course. Good luck to you, and sincere wishes for resounding success. |

When you get into prototype stage, gold plate it, put a gold chain on it and name the "Bad boyz bad azz gat" Find some rapper to demo it, and some nattering talking head like Geraldo rivera to denounce it. You will be rolling in bucks. Won't matter whether it works or not. "niggaz got a fo-five-fo niggaz got a fo-five-fo".......................................... |
