I have a box of Remington Nitro Express 12 ga.2-3/4" 00 Buck Shot box of 25, the box is white with a green line border, on the box it says Extra Long Range and Wet Proof, The Shells are a high brass with Remington/UMC around the brass on the sides, on the head of the brass it is stamped Nitro Express with a red primer, the hulls are paper and green in color, The box is stamped and marked U.S. PROPERTY on the front for the government, I think this box of shells was made for use in WWII between 1941-1944, If anyone here has seen or knows about these shells please post back to me, thank you ro.
