This video provides an accuracy test of Sellier & Bellot (S&B) .300 Blackout 124gr ammunition fired from an AR-15 platform. The reviewer found that this specific ammunition did not perform as well as Winchester 125gr rounds in his rifle, producing larger groups at 100 yards (around 3 inches) compared to the Winchester's 1.25 inches. While capable of hitting steel at 200 yards, the S&B ammo is deemed suitable for plinking rather than precision work with this particular rifle.
