remington 209 primers
Within every Remington, a primer is a group of subcomponents assembled to exceptionally tight tolerances. Primer cup dimensions are controlled to .0001″, and the priming mix is specially formulated for consistent ignition with a wide variety of powder types. Primers are tested for reliability from -20 degrees F to +150 degrees F. The unique tripod anvil design creates a larger strike area with maximum sensitivity, even with off-center firing pin strikes.

Use these in STS hulls with zero issues. More expensive than other printers, but I bit the bullet to follow recipes.

These are not only a very good shotshell primer, they are excellent in modern inline muzzleloaders. I have shot all the different powders for muzzleloader and these primers are most accurate than any other primer.
