Claim:
1. A cryogenically pressurizable projectile adapted to at least partially laterally expand upon impact comprising: an elongated body comprising a first, second, and third section, said second section is formed between said first and third sections, said first and third sections respectively have a first end and a second end section where said first end of said first section includes a forward tip of the projectile and said second end includes an aft end of said projectile on an opposing side of the elongated body from the forward tip, the elongated body having a first axis running through a center section of said first and second end sections as well as through a longitudinal center of said first, second and third sections, wherein said first section comprises an ogive shape rotated around said first axis; an internal cavity disposed within said body with a side wall section surrounding and spaced apart from said first axis, wherein said internal cavity further is defined by a first and second cavity end section that are on opposing ends of said internal cavity adjacent to said side wall section, wherein said internal cavity is formed extending into said first and third sections and through said second section within said elongated body; an internal cavity fill structure disposed through said second end section through a portion of said third section into said internal cavity; and a fill structure plug, screw, or closure section disposed within said fill structure adapted to receive and retain a cryogenic material into said internal cavity and retain structural integrity and remain fixed with respect to said second end section after said cryogenic materials generate a first internal gas upon thermal equalization within said projectile.
