I have one as well. Got it over a year and a half ago and I have had no issues whatsoever as far as the rifle is concerned. Brass is another story. I learned the 'Lapua' lesson early on.
My personal opinion is that issues arise when owners try to push the limits of the rifle past it's design limits and when loading parameters change as Green 788 points out. Pushing the limits of anything mechanical is a great American pastime but not always prudent.
IMO, it's a damned nice shooter, though a bit heavy, for a bargain basement price, hell, I've paid way more for a scope than I did for the 11 LRH.
It won't win a beauty contest either. My wife refers to it as 'industrial looking'.
Of course I religiously follow the 338 Lapua loading thread on this site. Lots of good information contained there. Borrowing from others experiences, I've loaded on recommendations in that thread with excellent results btw.
I don't shoot it everyday, even handloads are expensive compared to my 223's but when I do, it's always a hoot, it always draws a crowd at the club and some unlucky observer always gets 'washed' by the muzzle brake
I've yet to have heavy bolt lift, sticking cases or brass transfer on the bolt face (other than the usual swipe mark). I do anneal my cases regularly using Jeff's machine (thanks for the recommendation Jeff btw). All in all, the 338 has been a painless experience for me...... some shoulder discomfort arises after repeated use.......
