I have 60 rounds of Lake City Arsenal M2 ball ammo, 153 cleaned & tumbled cases, 51 primed cases, 12 rounds Remington 58gr. soft point Accelerator and 15 blanks, which the box is marked grenade launcher. I assume these blanks are used for military presentation events. I do not know if they are used for grenade launching. $80 includes shipping unless you want FTF in Southern Indiana sellersburg area here is a link to the ammo picture. http://s1221.photobucket.com/albums/dd461/davidb309/?action=view¤t=P1010223.jpg.
FYI on those blanks: grenade launcher blanks are not ceremonial blanks. Firing them as ceremonial blanks (with a BFA) will damage your gun. The pressure in these rounds is MUCH higher than the pressure of a ceremonial blank.
