Can anybody tell me the difference between a long action and a short action on a Winchester Model 70?

The Long And Short Of Rifle Actions
Dave Anderson
There's no industry standard on just what constitutes "short" and "long" actions. Most bolt-action rifle manufactures make at least two lengths, some three; Sako bolt actions come in four lengths to suit different cartridges.
American manufacturers seem to designate short actions of ones that will accept cartridges up to 2.8" in overall length, and long action as ones that will accept cartridges up to 3.4". By this definition, short-action cartridges would include the .30-'06 and its offspring, as well as magnums of similar length, such as the 7mm Rem. Mag. And the 300 and 338 Win. Magnums.
Typically, the receivers of short actions are 3/4" to 1" shorter than those of long actions. Since the bolt and magazine assembly are also shorter, weight is reduced by about 4 ozs.
Short actions are more rigid, enhancing accuracy. They are slightly faster to cycle, though not for the reason most people think. The actual extra distance the bolt travels in a long action is less than an inch, and since the bolt in moving fast while being cycled, the difference in travel time is insignificant.
The reason aimed shots can be fired faster with a short action is that the shooter's head doesn't have to move. The face can remain on the stock and the eye of the sight picture as the bolt is cycle. With long actions, most shooters have to lift their heads from the stock so the bolt has room to operate. Shooter must then reacquire position and sight picture.
