Hey Everyone, This is my first post on this forum so I guess I'll go ahead and introduce myself I'm Sydney and I'm getting ready to order my first fully custom rifle. I'm leanig toward getting a 7mm Rem Mag with a Bartlein stainless 5R barrel with a 1:10 twist. What barrel length would be the best for shots upwards of 800yards? Most people are recommending anywhere from 22" - 26". What's the best that you've found?
