Hey! That's precisely what Sockeye needs!!!
"Background: The FRAG-12 rounds have been in
development since 1994 by the Experimental Cartridge
Company, Ltd. and Action Manufacturing Inc., and have
recently been tested by the United Kingdom Ministry of
Defense (MoD) as a special forces application munition.
They are being offered in High Explosive (HE), High
Explosive Fragmenting Antipersonnel (HE-FA), and High
Explosive Armor-Piercing (HE-AP). The Marine Corps
Warfighting Laboratory contacted FRAG-12 and was able
to obtain 100 rounds of the High Explosive rounds for
initial testing. Based on early test results, the Experimental
Cartridge Company and Action Manufacturing are
updating the design of the FRAG-12 to allow safe firing in
weapons with Improved Modified (IM) chokes or larger."
