Ok, Im gonna start loading my AR-15 for long range. (up to 1000 yds)

I have shot at 800 with it but with 55 grain NBT's and want a better bullet for that distance as it is really affected by the wind.

What bullet/powder combo would you choose? right now I'm leaning toward getting the 69 grain SMK and the powder????

Just started delving into this as a friend has a 1000 yd range and wants to get together and have some shooting fun.

Oh, my twist is a 1/9"
