They are a couple hundred yards away. When they cleared my lot back in the early 80's all of the dirt was pushed into a 30' pile lining the back of property so I have a great back stop and nothing behind that for a few miles. I am just busting squirrels that like to nest in my shop and destroy my bird feeders. I looked up this post to see what your load was, got to the loading room and saw the old can of TB. Figured I would try to get that used up instead but its going slow at 3.4 grains a shot. Once that is gone I will fall back on the bullseye.
