I went for a possum shoot on a 200 acre property about 30 minutes drive from my house last night. It was a cool, still night with a full moon and I shot 11 possums (Australian Brush Tailed Possums, different to what you call possums in the US) and one rabbit. Rifle is a .22 BRNO Mod 2E with 3-9 Leupold, Parker Hale suppressor and a cheap, but very bright light that uses a 18650 battery. I was using Winchester subsonic ammo. Possum eyes reflect distictive red-orange when you shine a light on them. Some will run as soon as a light goes on them, but most stay staring at the light until you walk up and shoot them. Possums are quite tough and often need more than one shot to kill quickly. I got nine possums the week before.
