Some tips: At the base of some bushes in your yard that is the least visible by your neighbors, set up a feeding station for the squirrels on the ground this will get them in range and in a proper and safe area to shoot your air rifle. Next set up a card table back from the window or door stack up some books and a rolled-up hand towel on top this will be your air rifle rest., block the door open 10 -12in or more so you can see your feeding station and a safe area on both sides so you could see a pet, child or a visitor approaching your firing lane that you are sniping the feeding station from, start with a small target drawn on a paper bag with something in the bag to keep the bag from blowing away some potting soil works well, and take some practice shots. If you need to change your sights you move your rear sight the direction you want the pellet to go and this applies to scopes as well. Please use NO lead pellets these are safe for birds to eat. Now what I recommend is that you take the dead squirrels to a field or woodlot and leave them there fox,red-tail hawks, crows and critters will all benefit from your success and this way nothing is wasted. I wish you well and great success. and "Happy Easter" He Has risen from the dead.
