I once got under some guy's skin wicked bad. I was about 23. He was about the same. He showed up to the range with his girlfriend who could conservatively be called smokin' hot.
He shows up wearing black combat boots with black tactical pants, nylon belt, etc... you get the picture. Wannabe SWAT.
He opens up his range bag with an H&K USP and what must have been 20 magazines, all loaded up already. He looks over at me. Jeans and a flannel shirt, shooting my 19-3. Loading one round at a time, and just looking decidedly un-tactical. Kinda smirks at me and looks back to the GF.
He says, "ok hun, watch this," and he opens up on one of those targets that looks like the bad guy pointing a gun at you. At a range of 15 his shots look like a shotgun pattern at best. Many of them entirely miss the bad guy and land on paper but outside the lines. I'm sure some missed the target all together, but that didn't stop him from pumping through 100 rounds as quickly as humanly possible. When he turns around what does he see...
His GF is actually watching me. At 25 feet putting all the rounds in the same little clover leaf shaped hole. I used one of those "blue man" targets. Every round was in the orange circles. Over and over again.
He says "hey, you looking at this?" and blasts through another mag. She looks at him to humor him, but comes back to sanding behind me now.
He got so annoyed he packed up his gear and told her "c'mon, let's go."
It was pretty epic. I happened to be having a good night. I promise I'm not usually that good either. The timing just happened to work out perfectly.
I'll edit to add: Speed was not an issue here. There were a few where I put up a different target and banged through the cylinder as though it was an SD scenario. Accuracy still beat the heck of of him with his H&K. I'm sure it wasn't the H&K's fault. I'm sure the gun is more accurate than 99% of shooter who would shoot it. This kid was just a tool.
