And pretty obviously, I was driving those respective Barnes a lot slower than you were.
George,
I experienced something like that, 80 gr. TTSX at 3,600 fps out of my .240 Wby., not nearly 80 gr. at 3,900 fps,
I think the effect of speed on bullets can be a major factor regarding optimal bullet performance.
I try to match bullet design and velocity for the task at hand. The best testing lab is in the field, oberving how well bullets kill game animals.
Conventional wisdom has it that there is no mono velocity ceiling. Theoretically, maybe not; a mono won't blow up. Practically speaking, there seems to be a functional velocity ceiling in cases like this, low S.D. monos at warp speed.
Terminal performance is the gold standard, all else is speculation.
