I seem to be the odd man out, no surprise there. If shots are inside 250 yards, IME monos work fine at 2800fps MV. That probably gives an impact velocity of over 2500fps which has worked fine on smallish deer and plains game.
Shoot for CNS or bone and you don't have to over drive them.
They work well for me also at those speeds, the point is the art over driven with faster speeds like cup & core bullets are
