To Lawrence, I've been using super colibiris for a couple of years. I keep a Thompson Center contender carbine, in 22lr, next the back door for squirrels. They are quieter than my pellet gun and very effective if shot is behind the ear. Before any one gets upset, 3 years ago I got squirrels in my attic and they destroyed the insulation and phone lines. My count is up to 58 and counting.
Happy Fathers day. Don't forget to call your DAD, or Father inlaw.
