Seems to be a few cases at high speed above 3000 fps, doesn't worry me I am lucky to get to 2600 fps in my 7mm08 with a 162
I have blown up bullets in my old 22-250 as well usually 40gr HP varmit going over 4000 fps and no damage to the barrel. Blue smoke out the barrel and no holes on target.
So I will keep using them unless I have a problem
