Haen't tried the 270's yet but the .30 200 gr. Accubonds shoot exceptionally well out of my 300 Win Mag. Have them cruising out at 3,000 fps with RL-25 and hold inside 2" at 200 off cross sticks which is OK by me any day. I would bet the 270 Accubonds will shoot just as well. Am trying the 7 MM 160 shorlty for backup rifle for fall elk hunt.
