Anyone manufacturing the 44 AMP?

I got curious and went to the SAAMI website. Couldn't find a cartridge called 44 AMP. I'd like to know more about it.

The 44 AMP cartridge was developed for the Auto Mag pistol created by Harry Sanford. Made from stainless steel it was a huge pistol it wasn't gas operated that I'm sure of. The cartridge was a rimless version of the 44 mag similar ballistics. Had a interesting life as there were several companies that made,the pistol,sadly they are out of production and go for a premium price. There were rumors that someone was going to start a new run of the AMP but as of this date nothing has,happened.

I have the same set up as you, it's a pain in the butt to make the brass, made 50 of them and then found some one selling N.O.S starline brass.

Haven't looked lately for it and when I was I couldn't find it either.

To see the 44 AMP in action go rent Sudden Impact featuring Dirty Harry and a 44 Auto mag.

The Pistols were recoil operated and had two operating springs. The bolt was locked to the barrel until it got to moving via a bunch of lugs that made it looked AR15-ish when seen apart.

Light loads meant it was a manual repeater but with full strength medicine you knew you had fired it and all that weight up top meant the muzzle did come up a bit and then get slapped back down with the inertia of every thing going forward again.

A hoot to shoot that you could feel in your teeth and chest.

The wife of a husband and wife gunshop owning team used to keep one in a slot under the cash drawer. After she let me shoot hers abit I used to kid her about being ready for a robbery by a rhino.

There was also a necked down version called .357 Automag that makes the Sig .357Auto (or even a .38/45) look like a sad joke.

I did like it. Perhaps I was enfluenced by Mike Grells "Lost World " comic (DC?) where the main character had one. Exactly how an SR71 pilot could justify to his boss having a giant pistol and 120 loaded mags is actually more unbelievable than a hollow earth world with dinosaurs and folks of different historical development all living together, but hey, it was a comic book!

.....and if there where therapods about an .44 Automag might be a good thing to have.....

If anyone has a stray .44 automag cartridge they don't mind parting with (even just brass+slug), I have been wanting to add one to my collection for a while.

I've had quite a few Auto Mags over the past 25 years or so. 44 AMP, 41 JMP, 357 AMP, 30 LMP, and 45 Win Mag. I only have two now. One 44 AMP and one .357 AMP along with a couple extra barrels. I also made some AR-15 uppers in 44 AMP, 375 AMP, 357 AMP, and 30 AMP.

well, now I know. Thanks, everyone.

The Wildey was available in .44 AMP, and I've seen pictures of a revolver that was chambered in one, but I think it was a custom job.

The case forming setup you have is also useful for some other things. There are at least two .429" '.44' caliber wildcats based on cut-down .30-06 brass. They're designed to feed through AR or AK rifles for hunting in states that have "straight case" hunting seasons.
