Peterson Cartridge 300 Win Mag Long Unprimed Brass 50ct

Peterson 300 Winchester Magnum Long brass, unprimed, fifty cases to the box. Peterson holds a match grade standard through the whole run, from small batch production lines through their own quality control before the brass reaches a bench.

Brass is the one component in a handload that gets reused, so it is where consistency either starts or stops. Consistency, accuracy and case durability are what the line is built around, and small batch production is part of how that is done. Fifty cases is a working batch for a magnum: enough to develop a load, keep one lot together, and track how many firings the brass has taken.
