I think that's kind of a cool idea!
With a 14.5" barrel he should get some decent velocities, but he's going to have to deal with the proverbial hand-loading problem of the powder reaching it's pressure peak (especially H110 - that's a pistol powder) before the bullet gets out of the end of the barrel. In other words, the bullet could start slowing down before it gets out of the hole. There's a lot of friction in barrels when the bullet gets swaged down to the groove diameter. He may find that he's going to have to experiment with some slower burning powders..... Outside of the mechanics of making a cartridge work in a gun that is designed to fire a 5.56, he's really going to be left scratching his head until he gets the right loads worked up. Hope he's a competent hand-loader and understands propellant burning rates / primer pressures / bullet seating depths and all that stuff. |

People build ARs in 7.62x25, 9mm Parabellum, and .45 ACP, so I doubt there'd be *too* much trouble making a .44 AMP run...

H-110 is not a PISTOL powder, its used in some Magnum pistol loads, its also used in 44 Mag Semi-auto carbines and Lever guns with quite good results as well as many other cartridges both rifle and shotgun. I fail to see the mystic of the 44 AM cartridge. Its a rimless version designed to be used in the semi auto pistol, the AM. As cartridges go whats wrong with the 44 Magnum, 44 Special, 45 Colt, 45 ACP, 475Linebaugh. The Auto Mag pistol has a certain mystic, but not the cartridge. Too many pistol cartridges today will out perform it. IMNSHO

Tony Rumore on the forum here made some AR uppers in 357 and 44 AMP but no more.

In the case of an AR, it lets you build a light .44 Magnum carbine with fewer magazine problems than a .44 Remington Magnum with its rim. I don't know the details on how they're doing it, but since the AR magazine handles .50 Beowulf okay, I'd be astonished if it wouldn't feed .44 AMP as well. You'd want a stuffer block to keep them from slapping back and forth, but that's no big deal. For some of the carbine guys having both rifle and pistol in the same caliber is a really big deal; lots of them carry matched .44 or .357 combinations. Otherwise, if you're set up to reload .44 AMP anyway, why not? |

Nothing against using the AMP round, just thought it odd given the scarcity, and everything else involved with it.

If you reload, there's little difference between .44 Auto Mag and .44 Special...
My first rifle was in an obsolete caliber that required sawing off .30-06 brass, filing it to length, moving the shoulder back, and opening up the case mouth for a larger bullet. After that, just resizing an AMP case and shoving a new bullet in is trivial. <grin> |

I made an AR in 44 AMP back in 2000. I also made 6 of them in 44 Rem Mag about the same time. Then I made one additional 44 AMP and two 357 AMP AR's around 2005. I haven't built any AR's since then.......however, I do have a 375 AMP in work now.
Tony Rumore Tromix P.S. I built AR's in the following calibers between 1998 and 2005. 17 Mach IV, 17 Rem, 17 Tactical, 20 Tactical, 204 Ruger, .223, 6x45, 6PPC, 30/221, 338x39, 357 AMP, 44 Rem Mag, 44 AMP, 440 Corbon, 458 SOCOM, 475 Tremor, 50AE. |
