B.) Once its dawn start calling them in. You can make a homemade call for super cheap. Go to the hardware store and get a nylon screw. About 3 inches. Get a guitar pic. scrape said guitar pic along the nylon screw. You will recognize the sound they make when they chew on nuts.
C.) Make you a gun rest out of a sapling that is shaped like a Y. This will help you since you will be sitting stationary and may not have a tree to rest up against.
D.) Aim for the head!
If you hit in the chest - you ruin meat.
If you hit in the gut - you taint the meat.
E.) You can stalk if you want, but you have to be absolutely super stealthy. Squirrels are really smarter than people give them credit for once you spook them. They will go to the top of an oak tree and cling to a branch with their body blending in, not moving . I have searched for one with binoculars, laying on my back, for over 30 minutes. They can be patient.
