Peterson Cartridge Unprimed Rifle Brass Features The Peterson Cartridge Unprimed Rifle Brass is manufactured from quality brass and formed specifically for the .270 WBY Mag cartridge giving magnum rifle handloaders a dependable starting point for their loads. Each case accepts a large rifle primer matching the ignition needs of this high-pressure Weatherby magnum chambering. Peterson builds these cases to be reloadable letting shooters resize and reuse brass across multiple firing cycles when properly maintained. That reloadability helps extend case life and keeps load development more consistent from batch to batch. Match-grade quality runs through Peterson s entire manufacturing process from small batch production lines through a dedicated quality control department before the brass reaches a customer s bench. This 50-count box gives handloaders enough cases to develop and test a load without committing to a bulk purchase upfront. Reloaders working up magnum loads for long-range hunting or precision shooting benefit from the dimensional consistency this brass provides. For .270 Weatherby Magnum shooters chasing tighter groups and repeatable velocities this unprimed brass is a solid foundation for precision handloading.
