HAVE to shoot, hmm? If you dont HAVE to shoot, why RISK a long range shot's being LIKELY to miss, hmm? why dont you get CLOSER, if you HAVE to hit, and the guy's UNAWARE of you? If he IS aware of you, you wont HAVE a fully exposed, stationary target, ya know. all you'll have as a targetis either a head, bobbing around cover,or a dodging, fleeing torso. you dont hit either of those types of marks beyond 223 AR-capable ranges, even 10% of your shots. NOBODY can.
