Lineage
History
Introduced by Remington in 1906 for the Model 8 semi-automatic rifle. Designed with a rimless case to function reliably in the auto-loading action. The cartridge paralleled .25-35 Winchester in ballistics but was specific to semi-automatic Remington rifles. Discontinued as the Model 8 faded from production.
