The .260 has been becoming a popular caliber amount long distance competition matches. When I had one in a Ruger Mark II, it was nice. The caliber is good for whitetails up to 500 yards and slightly further. It's foot lbs of energy is still over 1,000 at 500 yards, but that's a velocity of over 1,800fps out a 24" barrel with 140gr psp bullets.
The deer I shot were down quick. Even took one straight on as it was the only shot I had for the moment and I wasn't in the mood for waiting long given his rack size.
