This review details the performance of Federal's 5.56mm 62gr FBIT3 (XM556SBCT3) ammunition in ballistic gelatin. Tested from a 10.5-inch barrel, the round demonstrated excellent barrier blind performance, immediate expansion, and consistent weight retention. It achieved textbook terminal ballistics, making it a top contender for self-defense applications, especially when compared to non-bonded OTM rounds.
