Since I own two of these I have a little experience. I own a 40x in a McMillan A5 stock. This gun will shoot 1.7 groups at 400 yd. with nosler 180 accubonds. My other one is a sendero that I shoot 165 nosler ballistic tips. It will shoot three shot .5 groups at 100 yd. If you are a reloader you will be okay. Rem. is probably going to deep six this round as the 300 wsm
is more popular. I beleive the rem. 300 saum is as easy to get shooting good as a .308, and not many are as easy. If you don't reload, I highly recommend that you look for another choice.
The upside of the gun you are considering is most of these guns will really shoot if you have the trigger lightened and skim bed the action. If it ends up being less than you want there are at a half dozen smiths on this board that will rebarrel it to a 6.5- 300 short mag. Dynamite!!!
just my opinion
