those ones with actual pictures are just wrong.
I know a lot of places wont let you shoot at targets that have a likeness on them, some wont even allow the silhouettes. Most of it is political correctness and insurance company driven, but even within the gun community, they seem to draw negative responses from some people.
Where they are superior to the plain silhouette type is, they present a realistic target, in more realistic positions, and with no scored aiming points, and force you to think and look for and shoot (or maybe not shoot at all) a more realistic vital/kill zone.
Its interesting that so many of these threads get so much heat going about which gun is better, for all sorts of reasons, but when you look at how most people practice and train, and what they worry about shooting wise, it kind of makes you wonder what all the fuss is about.
shooting targets isnt combat.
Shooting small groups on a static target at fixed ranges at your leisure isnt a realistic indicator of your skills either. Shooting each other with non lethal "weapons" comes about as close as you will want to get to combat, and its an eye opener to most "static" type shooters. Force on force type training with the better airsoft type guns, or if you have access to the more "painful" and realistic alternatives, take all this to a whole different level. Shooting tight little groups on a paper target becomes pretty much meaningless. All that shows is you have the basics down.
It all depends on what you want out of what your doing. All this arguing over which is the better gun is pretty much a joke if you cant actually use the silly thing.
