Frankly, I don't think it's all that important to hit a 3100fps threshold, but then again, my deer aren't that hard to kill, apparently.
For years and years, I used 4350 and 130gr. bullets, shooting at a bit over 2900, and killed deer without a qualm or wiggle.
I only switched from 4350 to H4831SC to be in the "cool" crowd, got a 100fps boost over what I was getting with 4350, except it's noisier and kicks harder. Kills stuff real dead, but not more dead than I was killing them with the slower loads. I even tried some 140s for a couple years, and they didn't kill deer any deader, either. After all, dead is dead, no degrees of dead, just plain old dead.
I guess, if you gotta have it, you gotta have it, but you won't need it.
Dead is dead.
