Has anyone heard of this cartridge?  Is it restricted to being a military/ LEO cartridge?  I read an a ticle about it a couple years ago, but haven't seen it since.

Here's the address of the manufacturer:

The local gun shop here (Bullet Trap in Plano,TX) has a .224 BOZ, 1911 pistol for sale(X-tra mags, ammo, and dies included). Fit and finish on the pistol was average, the thumb safety was small and was in dire need of some polishing as it felt a bit gritty when you engaged and disengaged the safely. Trigger was typical of any stock 1911, nothing to write home about. Overall, the quality of the pistol (similar to any stock 1911) did not match the uniqueness of the cartridge. They are rare, but you can find them.

Thanks guys for the hyperlink and the location of hardware chamberred for it.  When I first read about it, I thought it was destined to be limited as LEO or military.  It's one of those rounds that comes out that doesn't really compare with what's already out there, except for FN's 5.7mm.
