akka Posted September 8, 2018 Report Share Posted September 8, 2018 (edited) Can anyone tell me what this bullet is? It's .177 or 4.5 cal and 3/4" (19mm) long. Its steel of some sort with 5 annular grooves around it. Was found on a military small arms range. Not seen one like this before. Cheers, Akka.
