wish I would have taken video of a guy we had at the shooting range a few years back. My friend and I were waiting in line to shoot at the 25 yard range and this guy was missing the target completely. The range pro was telling him to adjust the scope and it wasn't helping at all, the "pro" was getting irritated to say the least. The guy went through a full 20 round box and part of the next box when the range pro finally said," Give me that gun and let me take a look."
The range pro put the scope up to his eye, then opened up the action to make sure it was unloaded, grabbed the guys case and put the gun in it. He then handed the cased gun back to it's owner and told him."The best advise I can give you is for you to sell your gun and take up another hobbie! Go home and don't ever come back!" (That's the PG rated quote, the real quote wasn't fit to be repeated.)
At this point we weren't sure what to think, so I asked, "What was wrong with that guyand his gun?"
His scope was mounted on the gun backwards! The pro said that looking through the scope the 25 yard target looked like it was 200 yards away and that you can't even see the cross hairs in the scope that way!
I think the pro felt like an idiot too, because they went through about 30 rounds before he figured it out and there were at least a dozen people waiting in line behind us.
