I'm no SEAL, but having been on active duty in SD and working here now as a contractor, I've met my share. If there's one thing SEALs are good at it's TRAINING; it's what they do. Whether that training is running, swimming or shooting, they train, they train a lot. A few of them have abilities they've been honing since childhood, others only since they decided they wanted to be a SEAL. I've watched BUDS classes dwindle in numbers as the weeks go by and candidates fall out. I've watched as a group enter the Pacific for a 5 mile swim in full gear. The point being they don't run, swim or shoot as well as they do without training. Yeah, the movies make it out to be easy for these guys to do superhuman stuff, but they are just humans who train hard. There's no trick to what they do, they train.

Believe it or not there are a lot of CCW folks who train and shoot competition. They might not shoot as much as SEAL, Delta or SAS, but we don't have their ammo budget. I used to shoot a lot of .22LR with a Ruger 22/45, then at the end of the session I'd break out Colt Gov't .45 ACP and shoot a magazine. Building good form with lower cost/recoil ammo, then shoot a magazine of full power. A 17 yard shot is very doable, but a headshot is not necessarily required. First it's more difficult to hit a head and second, unless the shooter is wearing body armor, center mass is usually a better target. But that is very situational. Before attempting that though you need to train.

But that's just my opinion and I don't train enough.
