Peterson Select casings are weight sorted at the factory. All casings in a 50-count box are guaranteed to be within one grain of each other. They are also sorted by overall length and guaranteed to be consistent to within .001 inch.
We’ve said all along that if your goal is to put multiple bullets in the same hole at the target, identical casing weight is not the most relevant factor – consistent internal volume is most important. And Peterson casings have always had excellent consistency of internal volume. Our weights, lengths and other case dimensions have always been more consistent than most of our competitors. But for those shooters who want to eliminate variation in length and weight we now offer PETERSON Select.
Pricing is slightly higher than our normal product because of the work involved in weight and length sorting. For maximum consistency from case to case, PETERSON Select is the way to go.
