Abstract
Applicant has disclosed a Method and Apparatus for stripping and feeding cartridges to enhance stripping cartridges out of a detachable double-stacked magazine, inserted into a (well opening of a) receiver of a bolt-action rifle, and to enhance feeding the cartridges into the firing chamber. In the preferred “apparatus” embodiment, Applicant's device comprises two protrusions (“bumps”) integral with, and radially spaced around, a bottom of the breech bolt head. When the rifle's breech bolt is pushed through the receiver, towards the firing chamber, a flat front face of a protrusion engages the rim of the top cartridge, pushing the cartridge out of the magazine, over the feed ramp or lip, and towards a firing chamber of the rifle. The protrusions alternate as to which engages the next top cartridge(s), due to the staggered (zigzag) columns of the cartridges in a double-stacked magazine.
