Yesterday I ran across (at a very reasonable price) two full bricks of Eley .22 Short Pistol Match ammunition, green box with black and white letting, no child warning. “MU-57” is stamped inside the end flap of each box. Would that be 1957? Along with those, I got two more bricks of Western .22 Short pistol Super Match, yellow boxes, also no child warning. Lot stamping inside the end flap was PK92, which I take as being 29 September 1959.
I actually plan to shoot these eventually, as I have several early .22 Olympic rapid fire target pistols. Big mistake or not?
