The standard shape of the air rifle pellet is not conducive to holding speed during flight. If behaves more like a shotgun slug than a rifle bullet.
Tumbling in flight is very much a problem with skirted pellets.
My experience is that lighter, and therefore faster pellets group badly compared to their heavier, slower cousins. This is particularly noticeable when comparing ( theoretical ) +1000fps against sub 800fps
But increased power from dieseling just makes noise, smoke and inaccuracy. I agree with MB: to despatch a wounded critter, a big stick would probably be most effective
