Ah, total metal jacketed.NYPD in AZ said:Taken from an online source:
TMJ is a thick (thickness varies by manufacturer) plating over the entire bullet. With FMJ bullets, the jacket is formed over the nose of the bullet and rolled over the edges of the base, leaving lead exposed in the middle.
With an "MJ", of course. Which I think is why it amounts to a jacketed SWC.joe sixpack said:i beleive it's just another term for flat nose..
