Sig Sauer Elite Match .300 Blackout 220gr Open Tip Match ammunition (brand part no. E300A2-20) is built for shooters who want their .300 Blackout rifle to shoot like a precision platform, not just a suppressor host. Sig Sauer loads a 220-grain open tip match bullet over brass cases, engineering the round for the uniform seating and consistent ignition that competitive and long-range shooters demand. Because the OTM bullet is built for flight consistency rather than expansion, it is a natural fit for target work, match competition, and disciplined practice at the range. Sig Sauer backs the load with the same quality control it uses across its Elite Performance ammunition line.
