Description
Within every 7 1/2 small rifle BR centrefire 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 wide temperature range. Individual primer pellet weight is controlled to 0.01g. A unique tripod anvil design creates a larger “sweet spot” with maximum sensitivity; even with off-centre firing pin strikes. And lastly, each lot is 100% visually inspected and subjected to critical ballistic tests.
