This round was built around the 175 grain Berger Match OTM Tactical bullet because it is the highest performing bullet available for magazine fed 308 rifles. The ammo is loaded to SAAMI specifications and the bullets are transonic stable which makes this a versatile overall performer for the common .308 Winchester. Berger offers superior ammunition for shooters that require reliability, accuracy and consistency. Berger ballistician, Bryan Litz, uses scientific techniques to develop each cartridge using only the highest quality components. Rigorous testing is done to provide consistent velocities and trajectories from lot to lot, so that each shot is as good as the last. Even though the Cartridge Overall Length for this round meets SAAMI specified standards, Berger recommends you check your rifle and magazine's maximum COAL for compatibility.
