I am attaching photos of a Prvi Partisan headstamp and a Lake City headstamp from some 5.56mm ammo I bought yesterday. They differ somewhat from the headstamps already in the gallery, so they may be worthy of inclusion.
The Prvi Partisan box is marked 20 CARTRIDGES ... 5.56x45mm ... BALL M193 ... Lot PPU 0503-07 ... NCD-021 ... MBL 0513. They are 55 grain, FMJ, and have red colored sealant on the primers.
The Lake City box is marked FEDERAL AMMUNITION ... XM193 ... 5.56mm M193 Ball ... 55 Grain Metal Case Boat-Tail Bullet ... LOT-139 ... FEDERAL CARTRIDGE Co. ... Anoka, MN 55303 U.S.A. They are 55 grain, FMJ, and have blue colored sealant on the primers.
