The answer to your question is both yes and no. The tang safety Rugers were push feed actions with a Mauser type claw extractor. Most of them had excellent accuracy and very reliable. I own over 8 different calibers in the tang safety Rugers and have intentionally tried to dump a loaded round from the magazine. If one cycles the action from full closed to full open, I haven't been able to do this regardless of speed of throw. The magazine controls the loaded round entirely from the time it contacts the bolt face until it jumps loosely into the chamber. The bolt has to be more than half closed before the round is detached from the magazine control, so the bolt face prevents the round from falling from the chamber, even upside down. So in this model Ruger, there really is no honest need to have controlled feed for reliability. As to short throws, a controlled round feed can be jammed just as easily in the later models.
