As far back as 1787 a Frenchman by the name of M. Magne de Marolles gave an account of choke-boring, though he argued against it. [3]Some sources state that the first pioneer was a Czech named Dominik Brandejs, who made shotguns with a choke in order to reduce the dispersion of shots, but his design was not popular in the 1820s.
The original model produced from 1947-1948. It had a plain one-piece pistol grip stock. The gun was distributed with two choke tubes (modified and full), which mount by screwing to the outside of the barrel, as opposed to the inside, like the Remington 870 or other modern shotguns. The shotgun was shipped with a wrench for removing the choke ...
In the extraction of petroleum (and other heavy-duty fluid handling contexts), a choke valve (or "choke") is an adjustable flow limiter that is designed to operate at a large pressure drop, at a large flow rate, for a long time. A choke is often a part of the "Christmas tree" at the wellhead.
The gap between the flange faces has been exaggerated by a factor of four to make it clearly visible. The choke flange can also be mated with a plain cover flange and still form a pressure seal. A choke connection is formed by mating one choke flange and one cover (or gasket/cover) flange. The central region of the choke flange face is very ...
In 1971, it was offered with the option of the Winchoke screw in choke tube system, supplied with a set of three tubes in improved cylinder (IC), modified (M) and full (F) choke. [15] [f] In 1973, 16-gauge was dropped from the production line. [15] With introduction of the Model 1300, a 3-inch (76 mm) chamber was made standard. [20]

An ideal choke would be a cylinder bore (the loosest) as the hunter wants the shot to spread out as quickly as possible. If this hunter were using a full choke (the tightest) at 20 m (22 yd), the shot would be very close together and cause an unnecessarily large amount of damage to the rabbit, or, alternatively, a complete miss of the rabbit.
