Recoilless Mechanism of the Anschutz LG380


This video shows the action of the Anschutz LG380. It was introduced in about 1981 and was the last of the generation of recoilless 10 metre spring-powered match rifles that began in the early 1960s with another Anschutz creation, the LG220, which was replaced a few years later by the LG250.

The LG380 achieved some significant success, including medals at major shooting championships in 1981, 1982 and 1983 (according to John Walter), but by the time it came out the writing was already on the wall for the use of spring-power in match rifles.

Walther's revolutionary single stroke pneumatic (SSP), the LGR, had been launched a few years earlier and was fast building a reputation for deadly accuracy, although the cocking cycle involved much effort. And soon after the LG380 had begun to make its mark, the Feinwerkbau 600 series SSP arrived and quickly captured the hearts of the world's top 10m shooters.

The LG380 is interesting because in one crucial aspect it trumps the action that it copies: the Feinwerkbau 300S. Both rifles involved a sledge action in which the cylinder slides rearwards on rails for a short distance, to cancel recoil with an equal and opposite reaction.

But whereas the FWB's action rides on top of the rails, visibly backwards towards the shooter's face, the LG380 contains the recoiling part of the action - the cylinder/barrel unit - entirely within an external shroud. So the shooter feels virtually no recoil and all the movement takes place out of sight and out of mind.
