Factory-seconds primers may have failed a manufacturer’s cosmetic inspection, such as off-color cups, minor finish blemishes, mixed lot packaging, or may have a slightly higher misfire rate, which is still incredibly low. They come off the same production lines as the name-brand primers they didn’t quite become, at a significantly lower price, which makes them a favorite for high-volume range ammo and practice loads. They’re one of the most popular things we sell. For match loads and hunting ammo where absolute consistency matters most, we recommend first-quality primers; for volume shooting, seconds are the best value in reloading.
