I go with my good ol' remington 581 .22. Currently i'm using Rem. sub-sonics for ammo. It's cheap, quiet in the woods when shot and is very accurate in my rifle. I very rarely use a shotgun, I just find it more challenging to pick shots out of a tree with a .22 then throwing a bead in the general direction and pulling the trigger. So in the early season, it's extra challenging with all the leaves. But it's still fun and that's all that matters!
