Bolt action rifle

A bolt action rifle comprising firing chamber means for the support of the entirety of the surface of the cartridge case during detonation exclusive only of such area of such cartridge case as must unavoidably by unsupported due to engineering tolerances in the fit together of manufactured components wherein said firing chamber means comprises a cavity formed by the abutment together of a non-rotating bolt, an extractor hook (26), a breech ring (18), and a barrel, said cavity sized and shaped to entirely surround, contact, and support the case of a cartridge inserted therein said cavity, said extractor hook attached to said bolt and movable therewith, said extractor hook adapted to seize said cartridge forcing said cartridge to move with said bolt during both movement of said bolt toward and away from said firing chamber means abutment-formed cavity such that the resulting controlled round feeding prevents double loading because an improperly retracted bolt ejects a firstly inserted cartridge before a second cartridge can be inserted into said abutment-formed cavity, said breech ring (18) having a flange adapted to fill entirely within engineering tolerances an undercut (20) in said bolt not filled by said extractor hook such that mutual abutment of said flanged breech ring 18, barrel, extractor hook, and bolt form the described cavity which provides support for said cartridge during detonation preventing cartridge rupture due to non-support and sealing said rifle mechanism to contain debris from a cartridge rupture, in which said non-rotating bolt comprises an outer bolt sleeve (37), geometrically an elongated cylinder bored to have an annulus therethrough, containing slidably within said annulus an inner bolt sleeve (43), said inner bolt sleeve having at a first end located near said firing chamber at least one dovetail slot (53) but into the body of said inner bolt sleeve, said at least one dovetail slot adapted to slidably receive a projection (52) integral to a locking lug (38) which locking lug 38 is in juxtaposition with openings in said outer bolt sleeve, and said lug being rotatable in response to sliding movement of said inner bolt sleeve such that forward movement of said inner bolt sleeve forces rotation of said lug through an opening in said outer bolt sleeve to engage a recess (40) in said receiver and lock said bolt from movement away from said firing chamber by bracing contact of said lug between said outer bolt sleeve and said receiver, the geometric fit of said lug in said at least one dovetail slot adapted to translate linear motion of said inner bolt sleeve toward and away from said firing chamber into rotation of said lug into and out of bracing contact between said receiver and said outer bolt sleeve such that said inner bolt sleeve serves to control said lug by axial movement of said inner bolt sleeve, wherein said dovetail slots 53 are wider at the base than at the top to capture and guide engagement with a projection 52 of lugs 38, slots 53 moreover being inclined radially with respect to bolt sleeve 43 such that the slide of lugs 38 in slots 53 as impelled by axial movement of bolt sleeve 43 urges a radial movement of lugs 38.
