Remington Model Rifle

The Model 740 Woodsmaster high power center-fire rifle, offered in 1955 by Remington Arms Co., Inc., Ilion, N. Y., is essentially an autoloading version of the Model 760 slide-action rifle introduced in 1952. Of hammer-less, solid-frame construction with side ejection, the Model 740 is gas-operated with dual action bars and multiple-lug rotating breech bolt locking into the barrel assembly. The detachable box magazine holds 4 cartridges. Safety is cross-bolt type, in rear of trigger guard.

The Model 740 was first offered in cal. .30-'06, but the list of chamberings

By Thomas E. Wessel was expanded to include the .308 Winchester, .280 Remington, and .244 Remington. Both standard and deluxe grades were available. At no extra cost butt-stocks could be had with high comb for use with scope sights.

Functioning cycle of the Model 740 is relatively simple. A measured portion of gas is tapped through a gas port in the lower midsection of the barrel when the gun is fired. This gas drives the action bar assembly to the rear, which carries with it the bolt carrier attached to the bolt with cam pins which work in cam ways in the bolt. These cam ways are cut to provide a slight delay between the time the action bar begins its rearward movement and the bolt starts to rotate. This delay allows the bullet to clear the muzzle, and chamber pressure to subside before the bolt begins to unlock. As the bolt continues its rearward movement the cartridge case is extracted and ejected and the hammer cocked. The action spring then forces the action bar assembly forward, at the same time chambering a fresh cartridge from the magazine. The rifle is now ready to fire.

No adjustment of the mechanism is required to properly function commer

cial ammunition with different bullet weights. Performance of the Model 740 with handloadcd ammunition is not always satisfactory unless the cartridge cases are full-length resized to dimensions of factory ammunition.

In I960, the Model 740 was superseded by the Model 742, which appears identical, but which does have differences in details. Perhaps the principal difference is that the barrel can be removed from the receiver without too much difficulty. This involves a change in the breech ring nut (28), which in the Model 742 is a hexagon nut that can be removed with a common wrench.

whereas in the Model 740 it was a capstan nut requiring a special spanner.

The earlier Model 740 rifles were quite sensitive to variations in the degree of tightness with which the fore-end screw was set up, and a spacing block had to be used.

In the later Model 740 rifles and in the new Model 742 this is accomplished by making the fore-end screw with 2 separate threaded portions, each thread having a different pitch. When the screw is tightened, the parts arc drawn together by the differential action of ┬┐he varying pitches, and the fore-end comes up tight with a small clearance remaining between its rear end and the front of the receiver.

The cam in the bolt which turns it to lock and unlock has been changed in form to give a smoother transition from longitudinal motion to rotary motion. the height of the ejection opening has been slightly increased, and other small changes have been made.

3 Next, lift out fire control unit by moving it slightly forward and tipping it slightly to clear disconnector (73). When reassembling, place safely (59) on "Safe" (red band nut showing) and. with mechanism in cocked position,-insert front end of trigger plate into bottom of receiver, rotating unit counterclockwise to clear disconnector. Push rearward, align holes, and drive in trigger plate pins

Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
