Hunter Safety 3 Practice Test

In rimfire ammunition, the priming compound is embedded in the rim of the cartridge base. When the firing pin strikes that rim, it ignites the primer, which then ignition the powder charge. This design means there isn’t a separate primer pocket in the middle of the base. Because the primer is part of the rim, rimfire rounds aren’t intended to be reloaded in a practical or reliable way. In contrast, centerfire ammunition uses a primer set in a separate pocket at the center of the base. So the statement is true because the primer is located in the rim, not in the center.
