Even back in the days before “Mad Men,” gun and ammunition makers were speeding up the .22 Long Rifle to, well, let's just say, questionable velocites.
“The Model 63 was designed for Winchester/Western Super Speed and Super-X Long Rifle; it’s stamped right there on the barrel. The first high-speed LR ammunition came out in 1930. If you look at those old ammunition handbooks and similar publications listing ballistic data, you’ll find the 40-grain high-speed .22 Long Rifle solid listed at 1,375 fps and the 37-grain hollowpoint at 1,400!
Did they really go that fast? I put this question to an engineer/representative of a major ammunition company. He prefaced his remarks with something about bovine manure …” .—C. Rodney James, “Winchester’s Classic .22 Semi-Auto Rifles of the Twentieth Century, the 63 and 1903,” from the soon to be released Gun Digest 2014!
