RE: Best long range deer caliber
I have a 270 in a Remington 700 ADL and it's very accurate. I've cut bullet holes at 100 yards lots of times. I think most Remington 700's in any caliber will do the same. I've lost count of the deer I've taken with this rifle. As for the 300's, I don't know why you would need something that powerful to kill a deer with.
