Abstract
This invention relates to a combination of a gun having a rifled barrel and a round of enhanced performance ammunition, and to a projectile for use in the combination. The invention is especially, but not exclusively related to a projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising: an elongate metal core, a ceramic tip with a Vickers Hardness greater than said metal core, said ceramic tip abutted with one end of the elongate metal core, wherein a deformable jacket or deposited coating, surrounds the elongate metal core and ceramic tip, such that said jacket or coating defines the nominal calibre of said projectile.
Claims20
A projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising:
- an elongate metal core;
- a ceramic tip with a Vickers Hardness greater than said elongate metal core, said ceramic tip abutted with one end of the elongate metal core;
- and
- a deformable jacket or coating that surrounds the elongate metal core and ceramic tip, such that said jacket or coating defines the nominal calibre of said projectile.
A projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising:
- an elongate metal core;
- a ceramic tip with a Vickers Hardness greater than said elongate metal core, said ceramic tip having a first end which engages with the elongate metal core and a second end which has a taper with respect to the first end;
- and
- a deformable metal jacket that surrounds the elongate metal core and ceramic tip, such that said jacket defines the nominal calibre of said projectile, wherein said jacket defines an inner cavity in projectile, and the ceramic tip is in the range of from 5 to 25% of the fill volume of the inner cavity, wherein during firing of the projectile lands of rifling in the barrel deform the jacket so as to impart spin on the projectile, and wherein during firing of the projectile the jacket is deformed into the grooves of the rifling in the barrel.
A projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising:
- an elongate metal core;
- a ceramic tip with a Vickers Hardness greater than said elongate metal core, said ceramic tip having a first end which engages with the elongate metal core and a second end which has a taper with respect to the first end;
- and
- a deformable metal coating that surrounds the elongate metal core and ceramic tip, such that said coating defines the nominal calibre of said projectile, wherein said coating defines an inner cavity in projectile, and the ceramic tip is in the range of from 5 to 25% of the fill volume of the inner cavity, wherein during firing of the projectile lands of rifling in the barrel deform the coating so as to impart spin on the projectile, and wherein during firing of the projectile the coating is deformed into the grooves of the rifling in the barrel.
