for squirrels i like to find a stand of oaks or other nut trees and just sit and wait..nice way to spend a fall afternoon..and you never know what else youll see in a stand of oaks in the fall..everything form turkeys to giant bucks you didnt think existed...i shoot my fair share of tree rats that way..after i shoot one if i didint see anymore i pick him up and move 50 yrds or so..moving really slow..or some days i basically still hunt through the stands of trees looking for them in the tree tops and the bushy tails bounding away...rabbits are pretty hard to hunt without a dog..i just get in some thick thick brush and jagurs and bust it...never do too good..only one i shot at was pheasant hunting and 7.5 shot and a imporoved choke at 40 yrd didnt hurt him..i hit him all 3 times..i could see the pattern in the dirt as he was running..my friends dad dumped his gun on him too..when i was pumping he shot and when i shot he got back on target..poor rabbit..it had to hurt...he never did stop..i know he caught a few pellets though...good luck...tree rats will be easier with an airgun too...i like using a 22 but an airgun with a good bit of power will take them...
