The .276 caliber Pedersen was the primary competitor to the Garand as the first US military self-loading rifle. It used a Luger-style toggle action. Its main flaw was that it required lubricated cartridges. This lubrication came in the form of a thin and hard wax coating which was not obvious to the casual shooter, but it was made a significant argument against the Pedersen and for the Garand rifle. The Pedersen also was heavier and used more parts than the Garand design.
