Originally, I became interested in the .224 BOZ, even bought dies and a reamer but never followed up with a barrel maker. About that time I became aware of the FNH Five-seveN, after that f-ing Muslim at Fort Hood opened fire and killed several American servicemen.
I am looking forward to a Five-seveN model that will accept a holographic sight.
Until then, I'm looking for a 10mm-.223 SABOT.
I like the idea of a super-sonic handgun round.
