Although I have a tendency to prefer CRF actions, there are times that its nice to just drop a round on top of the follower and close the bolt. My opinion has pretty much shifted now to where I believe that the feeding and extraction system of a particular rifle either works or it doesn't, and if it doesn't, it needs to be fixed before the rifle is used in the field. Thus no intrinsic advantage exists between one system and the other. Right now I'm playing with a M-70 XTR in .300 Winchester, which has proven to be a pretty smooth cycling rifle, and is a candidate for some mild customizing.
In hindsight, Winchester's mistake in 1963-64 wasn't the introduction of a push feed rifle, the mistake was calling the new push feed rifle a M-70. Had the push feed M-70 been sold under a different designation as an affordable alternative to an expensive CRF M-70, (retained in their super grade trim for discriminating riflemen) they would not have lost their market share to Remington, particularly when the push feed proved to be as smooth and accurate as the big dollar CRF rifle, or for that matter the 700 Remington. Instead, Winchester opted to abandon the iconic rifle that made them a commercial success in the bolt action field, then acted surprised when the consequences were the loss of the lofty position they held in the hearts of American riflemen and their wallets.
If we're going to compare the push feed M-70 to the Remington 700, the M-70 has a more positive extractor, and is more appealing to those who prefer actions with a flat bedding surface. The M-70's 3 position safety blocks the firing pin, where the M-700 2 position safety blocks the trigger, some prefer the Remington safety for it's position, but I think Winchester's safety is superior. The Remington 700 is a proven platform used in target shooting, varminting, big game hunting, and on the battle field as the M-40 the M-24 and the XM-2010. It has been used extensively for custom rifle builds, and I've owned my share of them over the years, but IMHO, the 700 does nothing that the push feed M-70 doesn't do equally well.
