It depends on your hunting situation. For myself I don't see the problem with a good high quality adjustable scope that goes up to a high magnification. The way people hunt here in Alabama has changed drastically in my lifetime. Most of our hunting is done now out of treestands and shooting houses. Places where you are shooting from a rested position at a stationary animal. Under those circumstances how does high magnification hurt you? I think it enables me to aim more precisely. As for the crosshairs jumping around more at high magnification? Well, I hate to break it to you but your point of aim is wobbling around just as much at 3 power as it is at 20 power. The only difference is that at 20 power you can just clearly see how much you really are moving. But the movement is just the same.

If you hunt heavy woods and take close shoots then yeah, by all means stick to lower powered scopes. You can get on target faster in thick woods and they will allow you to see better in the low light of thick woods where it will get dark much earlier than it does in a open field.

But for wide open spaces I have a Leupold 6.5x20 power scope that I dearly love. I like to be able to aim very precisely. Like the old saying goes, "Aim small, miss small." It's hard to aim small at 300 yards with a 4 power scope.
