Limited experience here but I was stunned by it anyway. One day two 270's shooting out of two boxes of 130 gr. bullets. Both averaged a hair over 2700 fps. Two .308's shooting out of two boxes of 150 gr. bullets. Both averaged over 2800 fps. This over the same chronograph with alternating shooters. All of these were factory loads and none were my rifles or bullets. Muzzle blast was a lot worse with the 270's. miles
