Ok, I am about to lose my mind with this 338 edge on a Remington 700 I just had built. When I first got it from the smith it would not eject fired rounds. I sent it back and the smith replaced extractor,said it appeared a little worn and my pressure might have been too high. Ok I got it back and developed a load and it worked fine for about 20-30 rounds and now it will not extract some rounds and closing the bolt on a round is pretty tight(which I noticed from the start). I asked the smith if it was possibly a headspace issue and he quickly said no way even though he has never checked the action cause I just sent back my bolt the first time. I am also seeing slight dimpling and extractor marks every 5 rounds or so, no bolt lift issues though. My load is only producing 2820 out of my 28" and it is using Remington brass with a coal of 3.785. What do you guys think. Please help me out.
