I haven't tried this bullet 180 gr. However my Barnes Manual shows it at 2762 fps. Its true though If you wanted to make a steady practice of shooting 180 grain bullets then the 30-06 would be a better choice . However the 180 in the 270 would have quite a bit higher sectioal density than the 30 caliber 180 grain bullet. 335 sd for the 270 bullet. 271 sd for the 30 cal bullet.
