Ok, so defying wind is one of the op's main requirements? No mention of him on how far he will be shooting these yotes and ground squirrels or targets.. Here goes: I shoot a schidt ton of the 69SMK's in my AR's and most of them have the 1 in 8 twist barrel, one has a 1 in 7. Lately I've been shooting them up in my 1 in 9 as well. I'll have to agree with trigernosis on this one, with that bullet choice. It's one competitors have been using for a long time, when shooting out to 600 yards. While I highly doubt the op is going to be shooting 1,100 yards, like some azz hats have suggested here, it may be a possibility. Probably pretty damn slim chances though. That's why I suggested the 77SMK pictured above, or the 77TMK that is like a unicorn right now. As for the 75 BTHP Hornady match. There are a whole lot better bullets out there boys. They fu cking suck donkey balls.. I've had way better luck with the 53 v-max and 73 ELD match, but to each their own. The 69's will punch sub 1" groups at 400 yards, are available (which is a huge bonus!!!!), as will the other bullets I am suggesting here. BTDT, so take that for what it's worth. Good luck to the OP. He may need a weed whacker to cut through all the bs in this thread..
