Now, however, with bonded and mono-metal bullets, the heavier 220-grain 30-06 bullet will perform no better than a 168-grain bullet which can be launched at a faster velocity. In fact, at 300 yards, a 168-grain Barnes TSX bullet fired from a 308 Winchester will perform as much as 15% better in terms of velocity, energy, and trajectory, than will most 220-grain bullets fired from a 30-06. The AccuBond is a bonded bullet and it’s suitable for any non-dangerous big game, but hunters don’t need a bullet that rugged when hunting deer with the 308 Winchester or the 30-06 Springfield.
