Daryl I have heard similar but only experienced the 2700 figure with a barrel whose shot out throat made a Weatherby throat look short. My second 270, a Steyr Prohunter does not like 130 grain pills- mono metals excepted- grouped about 1 1/2 inch at 100mts. The 110grains, 140 grains and 150's group around the .75"

When I finally twigged to the 140grain pills and how close they travel to the 130 velocities I wondered why the fook I ever bothered with 130 grain pills.
