I've been shooting one for about 2 years now. It shoots as good as I can expect from a factory rifle, usually averages 0.5 to 0.75 moa groups (if you do your part). As far as facotry ammo, mine will shoot the plain jane Rem Core Lokts 150 grain extremely well. I have worked up a good load using 180 grain Sierra GK over 74.0 grains of H100, WW Brass, CCI BR2, just off the lands. For what ever reason, it seems to like 150 grain bullets or 180 grain, but all of the 165's I have tried didn't work out.
As far as the rifle, I love the 40x trigger, very smooth. The stock is pretty nice, although I wish the comb was higher. Of course you could add a cheek piece. Overall, it has been a great rifle that has killed many deer and hogs.
The only thing I have done to it is dip the stock in a digital pattern.
