I love mine. I was at the range with it today, in fact. Our range has steel from 200-600 yards. 400, it was no problem. 570, the wind was kicking them off a bit, and I had to compensate for not really being quite 600 and long for the 500 yard sight setting. 605, I had the wind doped, and smacked it a couple of times.
This was from prone, slinged in, unsupported. This rifle is a real shooter, with a great two stage trigger.
It is heavy, though. I doubt I'll be hunting with it here. We hike all day, sometimes, and put in some serious mileage to find animals. A six to seven pound rifle (or AR carbine in the woods) makes more sense for most areas around here. If I were stand hunting, I'd probably not own another rifle to hunt with. What would be the point? My K31 was built in 1934, and shoots the GP11 like custom loaded match ammo. I paid 80 bucks for it.
