Sig Sauer Target 300 Blackout 125-grain Closed Tip Target ammunition (part no. C300B1-20) is a purpose-built practice load from Sig Sauer for AR-platform rifles and pistols chambered in 300 Blackout. The closed-tip bullet profile is designed strictly for target work, feeding consistently through semi-auto actions without the expansion or fragmentation behavior of a defensive round. 300 Blackout was designed to give AR shooters a hard-hitting, subsonic-capable cartridge in a standard-length platform, and this load is built to run that platform reliably through high-volume practice sessions. It’s a solid choice for zeroing a new upper, running suppressed drills, or simply keeping a 300 Blackout build fed at the range.
