"The Winchester Model 70 chambered in 7mm Remington Magnum with a 24-inch barrel and manufactured in 1965 represents the dawn of the controversial ""post-64"" era. Following major production overhauls in late 1963, Winchester radically redesigned the Model 70 to reduce manufacturing costs. This 1965 model features a push-feed action with a spring-loaded plunger ejector and a small hook extractor, deviating from the highly revered pre-1964 Mauser-style controlled-round feed (CRF) design."
