“There is huge demand for 223 Rem and 308 Win FMJ training ammunition, and we’ve had many requests for 300BLK as well,” said Brad Criner, Senior Director, Brand Management and Business Development, SIG Sauer Ammunition. “These premium training loads are designed to offer high-level performance at affordable prices.”

SIG supersonic rounds feature 125-grain Sierra Match King bullets, revered for their accuracy potential. SIG says the load maintains consistent bullet weight retention with minimal velocity variations, resulting from optimized shell case metallurgy with premium primers.
