Within every centerfire primer is a group of subcomponents assembled to exceptionally precise tolerances. Primer cup dimensions are controlled to four decimal places. The priming mix is specially formulated for consistent ignition with a wide variety of powder types, and tested for reliability over a temperature range of -20°F to +150°F.

Individual primer pellet weight is controlled to .01 grams. A unique tripod anvil design creates a larger "sweet spot" with maximum sensitivity - even with off-center firing pin strikes. And lastly, each lot is 100% visually inspected and subjected to critical ballistic tests.

Rifle primers are offered in 6 1/2 small rifle, 7 1/2 small rifle, and 9 1/2 large rifle and 9 1/2M magnum rifle.

Handgun primers are available in 1 1/2 small pistol, 2 1/2 large pistol, 5 1/2 small pistol, and 7 1/2 small rifle.
