For what you describe, it would be too much scope, I'll elaborate:
1. In hunting scenarios, animals tend to do what high mag scopes hate most: move out of the FOV. Finding an animal with too much magnification is a pain, and often leads to not taking shots, or - far worse for all involved - taking bad shots.
2. In "move and shoot" competitions, you will NEED lower magnification. At high magnification, small movements of gun and shooter make holding on target much harder.
I own 1 optic with max power >20X, and use it only when stable shooting positions will be used. If stalking, shooting from improvised positions, or shooting on the move, I go with lower power scopes.
All that said, it is a robust scope with very good turrets and good glass (I have owned 2 of the 5-20 SS scopes and liked them both.)
For "move and shoots", I prefer a christmas tree reticle that can be doped rather than the turrets, but that is me.
Personally, I would look for something more in the 3-15 mag range. For just a little more money, the Premier LT would be a good fit. If budget doesn't permit, I doubt you'd be dissatisfied with the SS5-20, just be sure to keep the power as low as possible.
