Nosler Custom Ammunition 257 Roberts +P 100 Grain Partition Spitzer Box of 20

Nosler Custom Ammunition is available in over 100 loads. The brass is cut to the exact SAAMI specifications, chamfered, deburred and the flash holes are checked for proper alignment. Primers are inspected and hand seated. The powder is hand thrown and verified for consistency. Finally the bullet is inspected and properly seated in exact alignment.

The entire loading process is personally hand-assembled by Nosler Ballisticians. The finished round is equal to the best of handloads. Loaded rounds are hand packaged in plastic ammo boxes with custom ballistic data printed in the label. This ammunition is new-production, non-corrosive in boxer-primed, reloadable brass cases.
