The same primers that Federal uses in their high-quality ammunition. Made to exacting standards for dependable ignition.
What are Federal 215 Primers used for?
Large Rifle primers ignite propellant more reliably and consistently in extremely cold temperatures. When Lapua began offering 6.5 Creedmoor brass, and interestingly, it introduced its brass with Small Primer pockets—to the acclaim of precision competitive shooters and to the dismay of traditional propellant companies.
Can you use Magnum Large Rifle primers in standard loads?
I recommend using magnum primers in all magnum loads and in standard calibers when using ball type of powder. This is to have a more uniform ignition and a more complete burn.
