I have had a lot of problems with the 6mm 115s, 7mm 180s, and .224 90gr bergers blowing up, but the 6.5s seem a little tougher jacketed to me. I have been pushing the 140s at 330 out of an 8T 28 inch kreiger 6.5 WSM. Only bloodied the rifle once (actually it was the wife) on a 450 yard antelope, but I was pretty impressed with its performance. I have not taken it out any further than 1150 but my wife shot some amazing groups in some strong but steady winds. I think I had 8 MOA of windage dialed in for her and she shot two softball size groups all around the bullseye. I just thought she could shoot her 6mmx284 and her 25x284. She shot those groups standing on a step ladder leaning on the side of my truck where I had the rifle in one of those cheapest caldwell rests sitting on the bed cover. I am going to try the .30 cal 230gr bergers this week in a 30-338 Lapua improved, I hope they hold together as well as the 6.5s.
BTW just as a warning you need a long throat to push the 140s 3300 out of a 6.5WSM I would not try it without a very long COAL.
