Hi all and I would like to start by thanking everyone in advance for any and all advice you guys can provide for me. I'm looking to do a 6.8 AR build and want suggestions on everything from lowers to uppers and everything in between. This is gonna be my hunting rifle and I hunt Mule deer and Elk ever year here in the great state of Colorado. I wanna be able to shoot up to 500yrds with as little as drop as possible (same thing I think everyone wants). So from the small amount of reading I've done thus far it seems a 1:11 twist would work great, but also seeing something about a 1:12 and 1:13 twist also? Again thanks in advance for any and all help/suggestions.
