I suppose my sample of one doesn't count for a whole lot, though I loaded up a few .277" 140 grain Accubonds for a friend's 270 WSM. The load was either 60 or 60.5 (can't recall exactly offhand) grains of RL-19, so the bullet was probably travelling about 3050-3100fps at the muzzle.
He shot a small whitetail doe at about 200 yards at last light while hunting with agricultural damage tags. Shot was a bit back, caught some lungs/liver, bullet broke a rib on the entrance and exit, deer dropped in its tracks. Index finger sized exit, insides were mush. He is happy with it so far, hopefully he'll have a few more samples with it this season.
