Well, you'll need the BCs for each of these, otherwise this is just a guessing game (or you try them out under somewhat controlled conditions....).  



Below is a link to a BC table that spans different calibers.



If you're shooting with varying ranges (hunting) than the pellet drop is also a factor to consider — and the heavy .30 pellets probably will drop a lot more than the .25 pellet ➔ so any error in ranging your distance to the quarry will affect your point of impact more. (If you're target shooting this is less of an issue.)
