Received my May 2024 copy of American Rifleman today in the mail. One of the main articles is honoring the 75th Anniversary of Ruger Firearms/Bill Ruger. One of the side articles on page 24 gives some history and such of Bill Rugers attempt sometime (according to him) in 1938-39 when he took a Savage 99 250-3000 caliber rifle and attempted to convert it to semi-auto fire. This was some 10 years prior to his first firearm a Standard Model 22LR semi-auto pistol (some call the Mark I). Interesting article. I've read of Rugers attempt to convert a 99 several times before, but always interesting to read about anything do with a 99 and of Bill Rugers genius firearm design abilities. The rifle is on display at the NRA Museum.
