When did the 1 oz 16 gauge "Baby Magnum" load come out?
The 12-, 16- and 20-gauge 2 3/4 inch Magnums first appear in the December 15, 1954, Western Super-X and Xpert ammunition price list.
Our ammunition companies all introduced the folded "pie" crimp on their Trap loads and 12-, 16- and 20-gauge Skeet loads circa 1939.
The world wide unpleasantness kept the pie crimp from being added to the high velocity hunting loads, Super-X, Super-Speed, Remington Express and High-Velocity until the 1946 to 48 time frame. As far as I can tell, even though our ammunition companies continued to offer 2 9/16 inch 16-gauge shells into the early 1960s, they never got the pie crimp.
