LOL, if a man has the skill, if you can see it and hit it, you can kill it with that old deep punching bastid.
10X for some reason has always been enough magnification for me, not counting if I were to build a specialty prairie dog gun or the like.
I've read about the lighter LRAB's, don't really know if they'd hold up inside 100 yards should a man need to hit a big ugly at warp speed, that 300 gr Accubond is a TSOB.
