    Well, I will cast an opinion for what it's worth. I think you have created a perfect storm. High velocity, 4 grove with deep scribing and a fast twist rate. The bullets are damaged in the tube from all this. I would recommend you go to the 300 OTM's. Their jacket is a little thicker and I think they will serve you much better.

    I think that he is using the OTMs. So he is out of luck on that unless he slows them down although that might not help either.

    That velocity of 2970 is at least 100 FPS faster than I would expect out of your load. It will be interesting to see how that works with drops when you take it to 800 plus.
