A 250 lb whitetail would be huge; they're fairly small animals. I can't imagine using anything larger than an ought-six unless for some reason you can't get within 400 yards of the animal and need the extra range of a magnum. Dad swore by the .243, the .308, the .30-06 and the 7mm-08 although he had many other rifles. Personally I've taken the most deer with the 6.5 Swedish Mauser. Never had one take more than a step after being hit.
