I’m trying to track down information about the MK255 RRLP (Reduced Range Limited Penetration) frangible 5.56mm ammunition reportedly used by SOCOM and the FBI, for both training and short-range (urban) combat use. There was a DTIC presentation on it in 2006: dtic.mil/ndia/2006smallarms/kim.pdf
I have come across two different DODIC numbers for this: AA40 (which seems to relate to the Mod 0) and AA17 (which seems to be the Mod 1). Can anyone confirm this, and explain the differences between the Mod 0 and Mod 1?
The bullet is jacketed with a frangible copper/polymer matrix core. The pics I’ve seen shows a rather blunt, grey-painted tip.
I know Black Hills has made this ammo, but has anyone else? And is it still being made and used?
This thread provides some information as well as lots of pics of the ammo and its boxes: calguns.net/calgunforum/show … p?t=891433
Secondly, does anyone know if the 5.56mm XM1037 Short Range Training ammo, which uses a fluted bullet and was expected to enter production in 2010, has actually entered service?
Many thanks for any help.
