20,000 rounds and still going strong. I've shot this rifle for 4 years in service rifle out to 500 meters, when I've got my ACOG mounted on the flat top, hitting a figure 11 military target at max range is a 99% deal when prone. From a 14.5 inch barrel, that is saying quite a bit.
I pity the poor Brits with their SA-80's. LOL! It barely works in the tropics, can't imagine how they are keeping em running in the dessert. My best pal is in 2 Para, and he's resorted to breaking his issue rifle down and using captured Russian stuff before in both Africa and Macedonia. Ridiculous.
My Accuracy International .308 shoots 1/8 MOA, which is about an inch at 800 meters and twice as good as I'm capable of firing it(the longest range our local comps go to for .308). I'll find some targets and post em up, but with my .223 rifle, what Rc51 has posted is about what any competent shooter can get themselves to with pratice, and is about how I shoot myself. Big B, the brainstem shot is called the "CNS" shot, or central nervous system. It's an area that comprises the brain stem, the sweet spot is where the spinal colum interfaces with the brain. Head on it is right between the target's mouth and nose. It's only about an inch target zone, so with a rifle and shooter capable of 1/4 MOA (most "elite" snipers are around there, average swatter is about 1/2 MOA), the furthest this shot is generally attempted is about 100 yards in a law enforcement situation, and 400 in the field.
That said, the guys at prarie gun works here in Canada have a .338 lapua rifle that our Forces have been testing ( a good pal runs
http://www.canadiantactical.ca check it out for pics/etc), and they regularly get and train to fire at the head out to 800 meters. Yikes.
The above is one of the .50 cal rifles the Canadian Sniper units use, a rifle just like this one (cough this one) is likely the world record holder for a kill on the battlefield, at least that's the rumour. Nearly 2700 meter headshot on a driver of a truck with a mounted 30mm gun that was firing on US forces in Afghanistan.
