While at the local range with my former fellow SWAT dudes this morning, whilst I was sweeping up brass, I ran across a handful of 5.56 rounds I am not familiar with.
It is a common 5.56 brass case, with visible annealing (military looking rather than a more polished civilian appearance). They are all head stamped WMA 16 with a red sealant around the primer. What caught my attention and therefore causing the befuddlement was the bullet- they are what appears to be 55/62 grain FMJ but with a dark brown tip. At first glance I thought they were black-tipped, much like the 30.06 AP rounds I have. I am relatively certain they are not plastic "ballistic tips" like a VMax. The very end seems to be not quite as pointed as a common 55/62 Gr FMJ round.
