In this shot, we see the animal off in the distance, which is why a good set of binoculars are essential and spotting scopes are commonly used. Cant tell much about this guy from this distance, plus the ever-present mirage blurs his image:

Here's a telephoto shot headon. Still cant really judge whats going on with his horns, not a good pose on which to make your decision:

This is a little better, quartering away, you can see the length pretty well but the other factors not so well:

This is the best view, and what you should wait for before you shoot, or not. You can clearly see that he has a nice set of prongs, the prongs are above his ears, the horns are fairly thick and the length is about twice his ears. Figuring the ears are about 7 inches long, this guy is about a 13-14 inch buck. This is about average for this area of Wyoming, not a record breaker by any means but if it was the last day of rifle season I would drop him. If I were hunting with my flintlock and got the drop on this fellow the first 5 minutes of the first day, he would be meat in the pan.
