300 m standard rifle

300 m standard rifle is one of the ISSF shooting events. It is similar to 300 metre rifle but there are more restrictions on the rifle (quite similar to those in 10 metre air rifle). The course of fire is a three positions program of 3x20 shots. This event is based in competitions with army-style rifles, and as such dates back at least to the 19th century, although the early championships had a true army rifle event, using the model of the host country's choice. The standard rifle event as such was created in 1947.

300 metre standard rifle is also on the program of the CISM military world championships.
