"Hornady Custom-grade ammunition provides shooters and hunters custom grade ammunition but in a factory offering. Each cartridge is loaded to ensure optimal pressure velocity and consistency from lot to lot. Each round is built to the tightest tolerances for peak performance rivaling and sometimes surpassing handloads in many guns. Much of the brass is made by Hornady the rest carefully selected for reliable feeding corrosion resistance hardness and the ability to withstand maximum chamber pressure. Like the powder each primer is carefully matched to individual loads and specially selected for their ability to quickly completely and reliably ignite the powder charge. This ammunition is new production non-corrosive in boxer primed reloadable brass cases.
