Extensive testing with a variety of commonly-used reloading powders has shown that these Remington® 209 Premier® STS® primers, in comparison with other commonly-used primers, create reductions of up to 40 percent in the high-to-low spread of velocities in reloads. This resulting improvement in velocity consistency is an important benefit to those reloading target loads for practice or competition. 209 Premier STS primers can be substituted for Remington's previous 209P primers without changes in published reloading formulas. 100 per pack.
Not Muzzle Loading primers...
These are not muzzle loading primers, they are shotshell primers that can be use in muzzleloading. You want these for best results with Blackhorn 209. The muzzleloading primers are not as hot as regular shotshell primers. But these rock with Blackhorn 209.
