Sig Sauer Elite SBR 300 BLK 120gr Solid Copper 20rd Box

The Sig Sauer Elite SBR load is a supersonic 300 BLK round for short barrel rifles. It uses a 120gr all copper bullet built for controlled expansion to about 1.8 times its original diameter, and Sig publishes its velocity from a 6.75" barrel, which tells you exactly what kind of gun it was built around.

An all copper bullet holds its weight as it opens, so it keeps driving after it expands instead of shedding fragments. That makes this a sensible pick for hunting medium game with a short 300 BLK, and for duty or home carbines where you want a bullet that expands reliably from a short tube. Each box holds 20rd.
