I prefer the CRF Winchesters, but the Winchesters are among the best of the pushfeeds. You won't have any problems with feeding or extraction as long as the gun is kept reasonably clean. If I were buying a pushfeed I'd seek out one of the 1980-2000 made Winchesters. They are undervalued and one of the best buys in used guns in my opinion.
Most folks completely miss the point of CRF. A push feed rifle is just as reliable in feeding, maybe more so. And from any angle including upside down. A CRF rifle has a more robust, rugged, and foolproof extraction and ejection system that "MIGHT" be an advantage if abused or if it had to be used in dirty, muddy, or icy conditions. Most folks will never notice the difference, but if hunting in harsh conditions I prefer the more rugged CRF design. But for more reliable extraction and ejection, not feeding.
If the price is right I would say go for it if you like the rifle. The only concern is that Winchester quality has been up and down really as far back as the late 1950's. Even the last 5-6 years of the pre-64's they were starting to decline. The 1960's and 70's were not the best years for quality. Most are fine, but there were some lemons made during those years as far as accuarcy and workmanship. In my experience the 1980's and 1990's pushfeeds are the best years before quaity started a gradual decline again in the early 2000's. The 2008-present FN made guns are excellent BTW.
