Here's an interesting new-ish caliber that doesn't get much attention.


22 TCM - from Wikipedia

The 22TCM (Tuason Craig Micromagnum)[1] is a proprietary bottle-necked cartridge developed by Fred Craig and Rock Island Armory. Before the cartridge was commercialized, it was called the 22 Micro-Mag. Standard factory loads are 40-grain jacketed soft hollow point. Armscor has announced a new round the 22TCM9R which will be the same case as the 22TCM but have an overall length of the 9mmx19 round. The company plans to release this round in summer of 2015 with a Glock 22TCM9R conversion slide to allow the 22TCM to fit in a 9mm length magazine, hence the "9R" designation. The 22TCM9R will in fact still be a 40 grain bullet but will be a fully jacketed hollow point instead.

The 22TCM is based on the 5.56x45mm NATO case, shortened so that the shoulder is at approximately the same length as a .38 Super cartridge. The cartridge is designed to feed from a Para-Ordnance-style double-column .38 Super magazine. Currently only Rock Island Armory catalogs firearms chambered in 22TCM: a 1911 style semi-auto pistol (also available with optional additional 9mm barrel and recoil spring), and a bolt-action rifle (which reportedly can use the same magazines as the pistols); and only Armscor (the parent company of Rock Island Armory) manufactures ammunition.
