I am torn between buying a 742, or 7400. Both are .30-06, 22" barrels. Both are in excellent condition, with the 742 being priced lower. I have heard stories, both pro and con on both models, however I would like to own a Remington Semi, for whitetail hunting. I know that it is important to keep the chamber clean in both models to insure reliability, but does one model outperform the other?
