Just picked up 15 of these 500 Nitro Express 3" shells and am looking for information on the age etc. I’d ask for (trade) value, but I’m in Canada so cannot ship to most of you anyway. Headstamp says KYNOCH 500 NITRO, no date or other marks. Copper coated steel projectile.
Forgot to check inside the boxes for date stamps etc. but the outside is stamped 2 R T and has the warning about point of impact on a sticker vs printed on the box.
