Every Remington primer has a collection of subcomponents that are manufactured to very tight tolerances. The dimensions of the primer cup are regulated to.0001′′, and the priming mix is precisely prepared for consistent ignition with a broad range of powder types. Primers are tested for dependability at temperatures ranging from -20 to +150 degrees Fahrenheit. Even with off-center firing pin hits, the innovative tripod anvil design offers a bigger striking area with optimum sensitivity.
