beretzs, I think you're right. If you hit a thin skin animal, or even a hog, at hyper velocity, stuff's gonna fly, even with a solid mono.
I think hyper velocity rounds are good for long range, fighting wind, etc. With turrets and range finders, you really don't need all that speed to reach way out there, except for cross wind. Getting there quicker is the best way to beat the wind, at least for a hunter without wind flags, etc.
A few years ago, I was shooting an 80 gr TTSX at 3,600 fps out of my .240 Wby. I shot a doe at 125 yds. I got a LOT of cavitation as they call it, but all outside the chest cavity. Had to find her in the woods at night with flashlights. Very little tissue damage inside the chest cavity, mostly a pass thru..
The S.D. on that bullet is less than .2.
So, on game it seems one has to balance bullet construction, even the S.D. with velocity for the acceptable terminal performance.
