Wild Bill,
I am struggling to get a grasp on your experiences. Between my family and friends, I would venture to guess that we have killed over a couple hundred animals with the 270. Antelope, blackbuck, Axis, black bears, TX rams, hogs, too many deer to mention and a handful of elk.
We have used bullets from 85-150gr, velocities from 1900 to 3250fps.
I have also personally killed deer with 22-375 caliber and most everything in between. In my humble opinion, there is not much better for deer hunting than a 270 with a 130gr bullet.
You have to shoot what you are confident in, so I respect your opinion and experience. But it simply does not mirror mine at all.
Nor those of most others. In my hands, Moose, white tails, mule deer, elk, bear and hogs have tasted death at the sound of a 270 round.
