Abstract
A ballistic optimizing system for use on a preferably bedded rifle comprising a movable weight element secured to the end of a rifle barrel such that said weight element can be moved axially along said barrel to change the effective weight applied for dampening purposes and having an indicator for indicating the relative position of said weight element on said barrel and further including an additional weight releasably secured to said movable weight element and ports through said weight element to allow gas escape.
Claims47
A ballistic optimizing system for a rifle comprising:
- a weight element of predetermined mass;
- and
- continuously infinitely adjustable means mounting said weight element on a barrel of a rifle to allow said weight to be positioned toward and away from a distal end of said barrel, the range of adjustability and mass of said weight being sufficient to compensate for inherent ballistic variances between at least two different brands of rifle ammunitions, whereby to effect minimum travel deviation for the projectiles of each of said ammunitions when fired through said rifle barrel.
A ballistic optimizing system mounted on a rifle barrel with an exterior surface, a graduated line scale on said exterior surface and threads on said exterior surface at the muzzle end of said barrel, said ballistic optimizing system comprising:
- a lock nut adjustably threaded on said threads of said barrel;
- means extending from said lock nut, including a portion cooperating with said linear scale as a position indicator;
- and
- a tubular weight element of predetermined mass, adjustably threaded onto said barrel in locking engagement with said locking nut.
A ballistic optimizing system for a bedded rifle barrel comprising:
- a weight element;
- and
- means mounting said weight element on a bedded rifle barrel to be infinitely adjustably positioned toward and away from a distal end of said barrel, between preset extreme limits.
A ballistic optimizing system mounted on a bedded rifle barrel with an exterior surface, a graduated line scale on said exterior surface and threads on said exterior surface at the muzzle end of said barrel, said barrel being mounted in a resilient bed carried by a stock, and said ballistic optimizing system comprising:
- a lock nut adjustably threaded on said threads of said barrel;
- means extending from said lock nut including a portion cooperating with said linear scale as a position indicator;
- and
- a tubular weight element of predetermined mass, adjustably threaded onto said barrel and in locking engagement with said locking nut.
A ballistic optimizing system mounted on the muzzle end of a rifle barrel, said barrel having an exterior surface with a threaded distal portion and a graduated line scale adjacent said threaded distal portion, said ballistic optimizing system comprising:
- a lock nut threaded on said threaded distal portion of said barrel;
- position indicator means extending from said lock nut comprising a skirt extending around said barrel and having an edge cooperating with said linear scale as a position indicator of said weight element, and further including index marks forming a scale around said skirt adjacent said edge;
- and
- a tubular weight element threaded onto said barrel and in locking engagement with said locking nut.
A ballistic optimizing system mounted on the muzzle end of a rifle barrel mounted to a resilient bed carried by a stock, said barrel having an exterior surface with a threaded distal portion and a graduated line scale adjacent said threaded distal portion, said ballistic optimizing system comprising:
- a lock nut threaded on said threaded distal end of said barrel;
- position indicator means extending from said lock nut comprising a skirt extending around said barrel and having an edge cooperating with said linear scale as a position indicator of said weight element, and further including index marks forming a scale around said skirt adjacent said edge;
- and
- a tubular weight element threaded onto said distal end and in locking engagement with said locking nut.
In combination:
- a rifle with a barrel having a chamber end, a muzzle end and a longitudinal axis between said chamber and muzzle ends;
- and
- a ballistic optimization device comprising:
- a weight element;
- means mounting said weight element on said muzzle end, said means being structured and arranged for locating said weight along said axis at a position appropriate to establish the center of gravity of said barrel to ensure minimum travel deflection for each of various rifle ammunitions;
- said mounting means comprising exterior threads on said barrel and cooperating interior threads formed in one end of said weight element
- means releasably locking said weight element against further movement toward and away from said distal end of said barrel, at a selected position on said barrel;
- wherein said releasable locking means comprises a lock nut threaded onto said barrel and engaged by said weight element;
- indicator means to indicate the position of said weight element relative to said distal end when said weight element is locked against further movement toward and away from said distal end of said barrel;
- wherein said indicator means includes a linear scale having equally spaced indices formed on said barrel and a second linear scale carried on a skirt projecting from said lock nut and telescoping over a portion of said barrel, and forming an indicator cooperating with said indices.
