New Here - Need Gun Recommendations for Predator Control

I didn't get the rangefider version. I ran ballistics on a 34 gr pellet at 850fps. If you zero at 50, pellet will be within 0.5 inches of POI from 20 - 50 yards. Energy at 50 was slightly over 40 ft*lbs (more than adequate for skunks etc). Am I missing something? I come from long range centerfire world so it is entirely possible I'm missing something. Thanks!
Ahhhh, I believe you shouldn't shoot Skunks in the head, I believe they tend to spray - Heart/Lung shots but it's your nose. :)
