Been in the smokeless game many years, primarily a bow hunter until I started.
without a doubt the meanest guns I've ever witnessed on an animal, would almost be cruel if they didn't kill so fast.
Have taken shots from 20 yards to 896 yards and they all died quickly but when you push a bullet that big, that fast, one would expect some carnage, just goes with the territory.
As accurate as any gun I've ever pulled the trigger on, .5 MOA or better in most cases.
