For example, factory and aftermarket receivers using the Remington 700 footprint are produced with various types of action threads, all with a 26.99 mm (1 + 1 ⁄ 16 in) diameter, but with a pitch of either a 1.588 mm (16 TPI, Remington standard), 1.411 mm (18 TPI) or 1.270 mm (20 TPI, Savage standard).

The Remington Model 700 is a series of bolt-action (later semi-automatic 74* series) centerfire rifles manufactured by Remington Arms since 1962. It is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.
In this design, the bolt head moves in a purely linear motion, and except for the bolt handle cam when opening or closing the action, operation by the shooter is also purely linear. The Heym SR 30 is another successful straight-pull design which features a bolt with ball bearings as locking elements. Here the primary extraction is performed by ...
The bolt was redesigned and made from multiple pieces. The large claw extractor was eliminated in favor of a small, but effective part mounted in a newly recessed bolt face. The ejector was now a plunger on the bolt face rather than a blade mounted in the receiver. A new adjustable trigger mechanism was fitted allowing for a sharper, crisp let off.

Based on the same principles as the Remington 700 series, the Model 710 uses a centerfire bolt-action cartridge, a 3-lug bolt system as opposed to the Remington 700's dual opposed locking lugs, with a 4-round detachable magazine (or a 3-round for the 7 mm Remington Magnum and the .300 Winchester Magnum). All can be equipped with a bipod and ...
The bolt face was enclosed so that it fully surrounded the cartridge rim, in a similar way to the Remington 700 bolt. While cheaper to manufacture than the undercut bolt face needed for controlled feed actions, it is also stronger, providing more support to the cartridge case head, and better contains escaping gases in the event of a case rupture.
The main disadvantage with a push feed system is the possibility for a double feed malfunction if the bolt is not fully closed when chambering a round, followed with pulling the bolt back to strip another round from the magazine, resulting in one chambered and one partially chambered round. A double feed in itself is somewhat uncommon as an ...
