Although many use it successfully, I soured on a 270 as an elk round when I saw a calf shot years ago with 150g partitions. On a slightly quartering away shot through the ribs at 325yds, the bullet didn't exit. I never chronographed these factory loads but I'd guess the were no faster than 2750fps or so. Perhaps the range and modest starting velocity contributed. When I help my son with loads for his 270, I hope to find a 150g load that shoots well as I'm a huge fan of exit wounds.
