308 starts at 2800 fps, is down to
about 2300 fps at 200m (if it's boattailed ball ammo) plain based sp's will be slower yet. 200m is 220 yds, 660 ft. The average velocity of the 308, over that 660 ft covered, is going to be 2500 or so fps. so the bullet's flight time is 1/4 second. If a guy is running sideways to you, he's a 9" wide target. If he's covering 25 fps, you need 6 ft of "forward allowance" to hit him. What does THAT look like in the sights, hmm?
If he's moving towards you,j(at a 45 degree angle, as in dodging) you only need half as much "lead", 3ft in other words. What does THAT look like in the sights? He can change directions every .5 second, so if you can't RELIABLY hit a 3/4 (of frontal) sized target, every .50 second, with your rifle, STATIONARY, you have no HOPE of hitting a dodging man at such ranges, except by luck. Say that the guy is moving at 20 or 30 fps. That changes the required lead enough to cause a miss. You do NOT group as well, on a camoed man target as you do on a bullseye. You do NOT group as well, extreme rapid fire, as you do slowfire. you do NOT group as well, on a mover, as you do on a stationary target. MOst of the time, if you go prone, you can't fire effectively, because vegetation, the lay of the land, wont let you. Other firing positions aren't nearly as steady as is prone, especially with bipod. That is why I say that you cant do better than 50% hits on a dodging man at 200m. All you CAN do is guess at the required lead, and fire a lot. Yes, you will hit SOME, but you will miss a lot. That all takes time, and his buddies are getting closer, firing, making you duck, and miss. This is all assuming that the enemy is stupid enough to attack in the open, in daylight. At night, you dont do nearly as well, even if you DO have NVD sights, or launch flares.
