POWDER CHARGE

When ignited by primer, powder charge, burning at a controlled rate, generates gas pressure which, with the aid of a wad column, propels shot out of gun barrel.

PRIMER

Gun firing pin detonates component in primer, which ignites main powder charge.

As we saw on the previous page, a shotshell is made up of several different components. There are many different variations of each component.

Packed with every MEC reloader are brochures supplied by leading component manufacturers. A study of this literature will show you numerous combinations of primer, powder charge, wad, and shot you should use with each empty hull, for waterfowl, small game, or trap and skeet. Each combination of components has been carefully tested by ballistics experts for maximum effectiveness and safety.
