RE: 270 for whitetails
My father-in-law has a .270 win. that he uses for hunting. IT used to be mine, but he had a .308 that I liked and had been wanting a .308 so we traded. This year he made the longest shot he has taken at a whitetail. He made a one shot kill at 350 yards. He shot from one ridge across the valley to another ridge. He held the crosshairs dead on.(no compensation or holding high) At the crack of the rifle the deer hit the ground. It was a 10 point with a 22 inch inside spread. It weighed 245 lbs. He was using a reload with a Hornady regular spire point bullet in 150 grains. I would say that the .270 win. is a great deer cartridge and one you would feel confident with. Good Luck.
