gilded metal jacket (GMJ) is basically the same as full metal jacket (FMJ) in that it provides a metal casing on a bullet core. The difference in the two metal jackets is the method of application. The full metal jacket (FMJ) is a casing that is applied to the core while the gilded metal jacket (GMJ) is plated directly on the core. For all intents and purposes, the GMJ rounds perform the same as FMJ rounds, but are less costly to manufacture, and therefore cost less to buy.
A magnum primer produces a hotter, more intense flame. This is produced by adding a powdered metal, such as aluminum, to the the priming compound. They are used to ignite larger charges or more "hard to light" powders.
