I use a Kimber of Oregon Model 82 with a Leupold 2.5-8X36 scope mounted on it. I have others that I use occasionally, but when I get I serious I get the Kimber. It is my squirrel gun, the others are rifles I can squirrel hunt with.
I hunt squirrels like other people hunt deer or turkeys. My camo stops just short of a gillie suit. I plan my hunts based on wind direction and speed, time of day, time of year, how much rain we've been having and whether I will have anyone with me or be hunting by myself.
I only take head shots, which means I have to pass on some squirrels. I don't shoot squirrels that will fall in the backwater or otherwise be lost. If at all possible I take young squirrels, those born this year. Until a recent mishap I used a rangefinder. It was a Bushnell Sport (169.00 on sale) and it was somehow misplaced on a weekend camping/hunting trip. I have shot squirrels at 80+ yards.
There are only two types of ammo that I use, Winchester Super X Longrifle hollow Points or CCI Velocitors. From my squirrel gun they both shoot great although they do shoot different points of aim. I have been using the Winchesters for many years. When testing the Velocitors I shot five five round groups with each brand from the bench at fifty yards. The Winchesters shot four groups that could be covered with a dime and one that was covered with a nickel. The Velocitors shot three that were covered with a dime and two that a penny covered. I can use the same point of aim from twenty-five to eighty-five yards with the Velocitors. They will greatly damage the meat if you get a body shot, but for head shots they are great.
This is probably more than anyone wanted to know about me so I'll shut it down. If there are any other diehard squirrel hunters and you would like to trade some trips let me know. Our season last until Feb 28th and I love hunting with new people. I always learn a new trick or two when I do.
