I've got one that was built by Greg Tannel at Gre-Tan rifles on a Rem700 SA and it's my best shooter. I shoot a 39 gr Sierra Blitzking at a hair under 3600 ft/sec from a 24-in barrel. My longest shot was on a prairie dog at 543 yards. There was a slight crossing breeze, and it took me 3 to 4 shots to get the windage right, and then that was it for the dog.
While coyote hunting, my dad, son, and I drove up on a bunch of feral hogs in an open field mingling with the landowner's cattle. Six shots later there were 5 hogs on the ground - 2 sows in the 175 - 225 lb. class and the other 3 were small pigs. It's a flat-out fun little gun to shoot - my daughters and my son have a blast with it as well. One of my daughters was pegging our prairie dog steel target at 300 yards a couple of weeks back.
