Sig Sauer 300 BLK 125gr CTT Supersonic 20rd Box

Sig Sauer's supersonic 300 BLK load runs a 125gr closed tip target bullet, the bullet weight most 300 Blackout rifles are set up around. Sig holds tolerances on case metallurgy and uses premium primers to keep velocity variation low from one round to the next, which is what keeps groups from opening up over a long string. 20rd box.

Supersonic 300 BLK is the practice and general purpose half of the cartridge, and this is a target load rather than a hunting one. The 125gr bullet keeps dispersion tight when a can is hung on the muzzle, so it works for suppressed practice as well as it does bare muzzle.
