No not hype but the 105 Amax does not have a high enough coefficient to be significantly affected by the aerodynamic heating. They are doing the same thing but the amount of the effect on the BC isn't as drastic as the others.

If the AMAX work in your rifle then keep running them as this discovery isn't going to make them all of a sudden shoot worse. I still plan on shooting my AMAX bullets I have on hand.
