Claim One:
1. A caseless round, comprising: a. a cylindrical-configurated hollow outer case having a fore end, an aft end and an internal surface, with said fore end open and said aft end closed, and with said closed aft end having an aperture therein; b. an aft grain charge shaped in the form of a hollow, open-ended cylinder and having an outer surface, an inner surface, an aft surface and a fore surface, with said aft grain charge disposed wholly within said hollow outer case, and with said outer surface of said aft grain charge abutting with said internal surface of said outer case, and also with said art surface of said aft grain charge abutting with said closed aft end of said outer case; c. a fore grain charge shaped in the form of a hollow, open-ended cylinder and having an outer surface and an aft surface, with said fore grain charge disposed within said hollow outer case, and with said outer surface of said fore grain charge abutting with said internal surface of said outer case, and also with said aft surface of said fore grain charge abutting with said fore surface of said aft grain charge; d. a primer charge disposed within said hollow outer case at the aft end thereof, and with said primer charge positioned at said aperture of said outer case aft end and within said hollow, open-ended aft grain charge; e. a booster charge disposed within said hollow outer case at the aft end thereof, and with said booster charge positioned in communication with, and fore of, said primer charge and within said hollow, open-ended aft grain charge; f. a flechette of high density material, with said flechette having a longitudinal axis, a fore end with a suitably shaped tip thereat, and an aft end with a plurality of fins thereat, and with said flechette centrally located wholly with said hollow, open-ended fore grain charge; g. a sabot, with an open fore end and an open aft end, comprising a plurality of identical constituent portions disposed wholly within said hollow open-ended fore grain charge, and surrounding said flechette in a snug fit, with said open fore end of said flechette shaped to catch air and positioned at said open fore end of said sabot, and with said aft end of said flechette protruding from said open aft end of said sabot; h. a first seal fitted over said sabot and disposed wholly within said hollow open-ended fore grain charge, with said first seal having a rotating band ring external of, abutting with, and integrated with said first seal, and with said rotating band ring abutting with said inner surface of said fore grain charge; i. a fore boot seal fitted over said open aft end of said sabot, and interposed between, and press fit between, said first seal and said sabot; j. an aft boot seal having an open fore end with a forwardly disposed air-catching circumferential groove thereat, a closed aft end, and a cavity in communication with said open fore end, with said aft boot seal comprising a plurality of portions loosely fitted around said plurality of fins of said flechette, and with said fins wholly within said aft boot seal cavity, and also with said aft boot seal portions abutting said inner surface of said fore grain charge, thereby releasably uniting said aft boot seal portions; k. and, a second seal disposed at the open fore end of said fore grain charge, thereby closing said end.
