Fair enough. I should have specified some probability interval around it......
Though as a serious 308 shooter I do know what he's trying to do is much like pissing to windward.
It won't be easy but I'll do it. Because most haven't done it does not mean it can't be done. The whole .308 is only good at X distance seems to be an American thing, in other countries they shoot .308s until they fall. It's not hunting or trying to kill anything, it's for fun and it's going to happen. I video all the long distance shots with .308 I take so I'll have it on video. My goal is a target big enough that I can see at a mile and 16" targets are still pretty big through 15 mag, but small enough to be an accomplishment. Have faith, it'll happen...hahah, might take 4 years but it's happening.
