I shoot a 20 Tactical, which has similar ballistic performance. As said above, great for prairie dogs. I love 223's out to about 350 yards. Yep, they'll shoot farther than that, and many will tell you they shoot it successfully past that. I can't. From 350 out to 500 (maybe stretch a little further) a .204 will still knock em down, and will do it even with some wind blowing, and with a much flatter trajectory at that range.
