Buy CCI Large Rifle Bench Rest Primers Online. There is no such thing as a “too small” group in Benchrest competitions. Everything must be fine-tuned to perfection in order to generate match-winning outcomes. Use CCI Benchrest primers for this reason. The priming mixture is poured into the cups by only the most trained and experienced workers, ensuring that each shot produces the identical flame. Benchrest Primers use carefully chosen cups and anvils for enhanced uniformity.

Today’s CCI primers are thus more sensitive, simpler to seat, and compatible with progressive and automated loading equipment than ever before. For the cleanest possible burn, they use non-corrosive and mercury-free contemporary initiator mixtures.
