The one thing I can promise you is that it is not caused by 'overspinning' the bullets. That is a myth that has been promulgated for many decades. To over-spin a bullet, you would need an extreme twist rate, much faster than your 1:8" and you wouldn't notice it at anything under 400 yards even then. Since there are far too many armchair experts out there, your best bet is to always go to the manufacturers. Clean your barrel thoroughly first to see if that helps; if not, you should contact Hornady to see what their recommendations are and if you're using the bullets out of parameter in some way unbeknown. If that doesn't work, you might also need to take it to a competent gunsmith.My 28 nosler has approximately 120 round down the tube as of today. Its a 26" proof 1:8. The first 100 rounds did well, mainly for load development, zeroing, etc. I've been using 1 box of Hornady 180 ELDMs (just opened a new box for these last 20 rounds), N570, with ADG brass. My 180's are from several different lots (tough times finding bulk supplies).
As of now, my load with 82 gr of N570 is pushing the 180's to 3130 fps.
Today at my local range I was finally setting the zero stop on my scope. These rounds were with the new box of 180 ELDMs. First 3 rounds were fine, made and adjustment, then I get this on the target, 3 inches high, when I have yet to touch the elevation:

At first, I thought the bullet just tumbled. Well, it did tumble, but it was also coming apart. Upon closer examination, you can see the gray marks on the paper when part of the jacket impacted the paper, with a shape that is not just a tumbling bullet. Started to think well, may be it was due to me recently stripping down the barrel and just shrugged it off.
Went 5 for 5 with no issues. Even let the barrel get rather warm during that string too. It was fine. Then the next 3 groups of 3 had issues, with at least 1 round going way off target and never making the paper. I had a friend observe the impacts as well.
I was lucky enough to catch another separation on paper. This one you can clearly see the gray marks on the paper where the deformed jacket was striking the paper.

Has anyone else had this problem? I've read about 28 noslers having ELDMs blowing up completely when speeds exceed 3200 fps. I'm also aware that QA/QC has probably gone down the drain too, given the state of the industry.
With this experience, the expense to shoot this rifle, and me needing to have it dialed in before November, I ordered 150 rounds of 177 gr hammer hunts. At least with solids the odds of them coming apart are slim mid flight.
Remember that enthusiasts only have so much experience; they might help but they may not; so always consult manufacturers who have far more experience and insight.
