I have tried them in my 6.5-06 AI and they foul really bad at 3100 FPS. I have a friend with a 264 WM who has the same problem. They shoot great in my 6.5 creedmoor and don't foul as bad so we think the speed is what makes them foul.
I would be interested to see your results with the high speeds of the nosler.
Does anyone have any load data for a 26 Nosler using the new Hornady ELDx and ELD match bullets? I talked to hornady and they said 1-2 yrs to get any data from them.
I have been shooting the 143gr ELD-X in 6.5CM and 260 Remington. There have been no problems and they shoot great in my rifles. Now, the 26 Nosler is good to 850 yards BUT extremely inconsistent afterwards. I was worried about the bullet tip deforming due to the extreme velocity (3300fps). That seems to be well founded. Per Hornady, "At 3300 fps you could be seeing some tip shape change problems. The temperatures at those velocities are close to the melt point of aluminum." Normal velocities ~2850fps don't seem to be a problem and very accurate. But, with the 26 Nosler, I will stick with the 140 VLD. By the way, the load is 85.0gr of US869 and an average velocity of 3320fps.
I have made a few different loads the 143 eldx and 140 eld match for the 26 nosler and I am getting extreme fouling after 8 shots.the speeds start out at 3264,3303, then drop drasticallyand after the 8 shots the barrel is completely fouled with copper so much so that the rifling is gone.
