I received some of this ammo today after finding it listed on Armscor’s Advanced Tactical website. It is almost exactly the same as the original 22TCM, with the obvious exception being the headstamp and the shorter rounded-profile projectile. The projectile was the major change to make it more compatible with Glock type mechanics, which this is intended for with the Rock Island Glock upper conversion. The angles & spacing on the head area / extractor groove look a little different as well in the side-by-side close up that I took.
One interesting thing is that on the box there are stickers to cover up where it is originally printed “39 gr Full Metal Jacket” and the new sticker instead says: “Jacketed Hollow Point”. So for whatever reason they have printed their first run of boxes incorrectly (collector item?!), or else were planning to do FMJ, but then decided on JHP. I would think the reason would be either to appeal more to a self-defense roll as opposed to target shooting, or perhaps because they are cognizant of the fact that this ammo blasts through Kevlar vests, people, walls, cars, etc… and wanted to temper that a bit with a HP projectile (which is still the highest penetrating pistol-projectile on the civilian retail market).

Meanwhile, the Armscor brand .50AE box of ammo which I also ordered has arrived with Starline headstamps, despite their online help-desk chat operator’s assurance that the cases were “Armscor brand”…
