Model 70 Classic
In 1992, Winchester began producing a controlled round feed Model 70 that was marketed as the "Classic" model. This version reintroduced the CRF feature, while retaining the "anti-bind" locking lug groove bolt guide of the 1968 push feed model. The use of modern CNC manufacturing techniques allowed Winchester to re-introduce the CRF feature at a competitive price.
Around this time, Browning, which is owned by the same parent company as USRAC, Giat Corp, of France, introduced the BOSS accuracy system. The term ‘BOSS’ is an acronym for Ballistic Optimising Shooting System. The device attaches to the muzzle end of the barrel and allows the natural harmonics, commonly known as barrel whip, caused during the bullet’s passage down the bore, to be refined and controlled. By adjusting the device for optimum performance in the individual rifle, accuracy is brought to peak level. Winchester Model 70s equipped with the BOSS provide a significant improvement in accuracy for a production rifle. Currently, only Browning rifles are available with the BOSS.
Later, Winchester expanded the Classic line, putting the Classic action on all their modern stocks, giving a wide range of choice in rifle types. This basically lets the buyer choose an action, then choose a stock to one's liking. Both pre- and post-'64 versions of the Model 70 actions have their strengths and weaknesses.[8]
[edit]1992 Classic Model (Controlled Round Feed and Controlled Round Push Feed)
At the same time as the CRF feature was re-introduced, a recent innovation allowed the short extractor used on the post-'64 models to ride over the extraction groove on a cartridge, giving controlled feeding without the expense of the long Mauser type extractor. This was called Controlled Round Push Feed. This is achieved by the use of the post-'64 extractor, combined with the pre-'64 bolt face relieved at the bottom allowing the round to engage the bolt face from underneath.
