Revision as of 06:23, 22 March 2021
The 10mm Magnum looks to be a fairly obscure centerfire pistol cartridge, with origins appearing to go back to Arcadia Machine & Tool (AMT), in a version of their Auto Mag series of pistols - (the AutoMag IV? It's unclear if the cartridge has ever been referred to as the 10mm AutoMag, so that needs confirmation.
The cartridge is (mostly) a lengthened 10mm Auto, made to achieve significantly higher velocities, and to be suitable for hunting, competition shooting for silhouettes, and so on.
It should be noted that a longer case length is not the only change to the case. It also has a thicker internal portion of the rim and flash hole, as is shown in the image second down on the right of this article.
Experimentation by Colt
Colt seems to have briefly experimented with this round in their Colt MARS "Mini Assault Rifle System" PDW program in the late 90's, by necking down the cartridge to accept a .355 caliber projectile, creating their 9x30mm MARS cartridge. This round was the counterpart to their other experimental PDW-style cartridge, the 5.56x30mm MARS, which was essentially a shortened 5.56 NATO round that fired at reduced velocities to be suitable for their new design's smaller form factor and lighter-weight.
Ballistic Performance
Ballistically, the 10mm Magnum offers a significant increase in energy over the 10mm Auto, and is comparable to (and even exceeds) many .41 Remington Magnum loads. One such example in .41 magnum is Barnes Vort-TX 180 Gr. HP's at 1520 fps, for 923 ft lbs of energy.
Below is information from Reed's Ammo, which will be referenced and linked to in the "Resources" section at the bottom of the article. As of writing this, they appear to offer two load options, one with a 180 gr. hollow point, and another with a 200 gr. hollow point. Ballistic data is in the table below.
| Bullet Weight / Type | Velocity | Muzzle Energy |
|---|---|---|
| 180 gr. | 1,625 fps | 1,055 ft lbs |
| 200 gr. | 1,620 fps | 1,165 ft lbs |
Ammunition Availability
Reloading: It doesn't appear there is any clear or simple way to create casings for the 10mm Magnum, but this needs additional verification.
Loaded Ammunition: It appears that loaded ammunition is available from a company called "Reed's Ammunition & Research, LLC" in two loads, which are referenced above in the "Ballistic Performance" section. A link to their site is in the "Resources" section at the bottom of this article.
