The sniper is apparently shooting 100-200 yards. The round is totally adequate at that distance for a medium weight target, although for heavier targets such as moose or elk it would not be adequate. One question is whether the 223s are factory load or hand-loaded. Hand loads can produce much greater repeatable accuracy; factory loads have a wide muzzle velocity spread that would adversely affect longrange shots. But 100-200 yards isn't long range. 100 yards is a pistol shot, although 223 in a pistol would be kind of harsh on the shooter and still wouldn't have the power of a long barrel weapon.

Not really. I've shot .308 in pistol and found it to be quite comfortable. Shots with a pistol above about 50 yards usually requite quite a bit of practice though. If he's using pistol, he's quite a bit out of the ordidnary in his training.

When I go shoping for amo for my .243, I get two choices, 80's and 100's. When I bought the rifle, I went to the range to zero it in, is used 80's, when I went to CO. to hunt deer, we all checked out our zero's, when I checked mine I used 100's, at about 50 yards, I was 12 inches high, the 22's loose trajectory, very quickly, of course, this is my personal experience.

There are a lot of FReepers on this thread with more knowledge than I have. All I have is experience.

Sorry, but a 100 yard shot is only a pistol shot if you are very lucky. While you are shooting your pistol at me at 100 yards, I will nail you with an arrow. Sorry.....
