I got 5 squirrels in November then 6 in December then none in January. So I was happy to get this 18 ounce male this morning. Double lung through shot with my P35-177 using 10.6 grain H&N Baracuda Match pellets that leave the barrel at 880 fps. It was sitting up on a limb eating an acorn. It ran a few steps down the tree and fell stone dead. Typical reaction in my experience to double lung shots when you don't hit the shoulder at least with a 177.
