3. Get close
Handgun hunting is productive now because quiet footing, thick foliage, short timber, and oblivious young squirrels allow a stealthy hunter to get close. But you still have to make the shot. For that, you need a good gun (see sidebar) and a solid rest. I create a two-point rest against a tree by placing both the underside of the gun barrel and the front edge of the trigger guard against the tree trunk, with my off hand bracing below it. It's an unusual hold, as the gun is slightly canted. But I haven't found a better way to steady a rimfire handgun for a shot at a squirrel in the treetops.
