What is claimed is: 1. A process for assembling ammunition, the steps of which comprise: a. providing at least a partially assembled cartridge, one end of which having a pocket dimensioned and disposed to receive a primer cup; b. providing a primer cup dimensioned and disposed to be received by said pocket of said partially assembled cartridge, in said primer cup is disposed a primer mix; c. applying a composition over the primer mix disposed in the primer cup; d. exposing the composition to UV/visible radiation, sufficient to initiate cure; e. permitting the composition to cure under anaerobic conditions; and f. inserting said primer cup into said pocket, wherein said composition is a UV/visible radiation and anaerobically curable composition, comprising: a. (meth)acrylate component; b. an anaerobic cure-inducing component; and c. a photoinitiator component comprising a UV/visible light cure photoinitiator. 2. Ammunition comprising: a bullet forming the front end of the ammunition, to which the bullet is attached to a cartridge casing; a cartridge case forming the back end of the ammunition, in which is a primer pocket dimensioned and disposed to receive a primer cup; a primer cup dimensioned and disposed to be received by the primer pocket, in said primer cup is disposed a primer mix and an anvil; and a UV/visible radiation and anaerobically curable composition, comprising: a. (meth)acrylate component; b. an anaerobic cure-inducing component; and c. a photoinitiator component comprising a UV/visible light cure photoinitiator dispensed over the primer mix and anvil in the primer cup, after having been exposed to radiation in the UV/visible range of the electromagnetic spectrum, and anaerobic conditions.
