Remington 209 primers are regarded as some of the best by both muzzleloaders and shotgunners. Features like a superb fit between the battery cup and the priming cup (fit held to three decimal places for consistent performance), a consistent priming mixture for standard performance over a wide variety of reloads, a foil covered flash hole that prevents powder intrusion and an anvil that is made from cartridge bass for strength and is 100 percent inspected during manufacturer make it well respected and sought after by top competitors. Per 1,000.
I shoot thousands of rounds of trap each year. My son shoots as well. Reloading is essential to keeping costs down and fine tuning the loads we use for optimal results. We reload only Remington STS and Gun Club shells and the Remington STS primers are the perfect start to the reloading process. I've never had a miss fire with these primers and they seat in the primer pocket perfectly. One review complained about the cost. Yes, they do cost a bit more, but they are made entirely from the same brass as Remington's metallic cartridges. I save the punched primers and recycle them at a metal recycler. A full 5 gallon bucket of ammo brass can easily defray the costs of buying new components. Highly recommend these primers. Happy reloading.
Primers are the first thing to go in a shell when you are reloading, so we always start with Remington 209 Shotgun Primers. It is important when you have a kid in trap to teach them responsibility and reloading is a great way to do that.
