Hey guys. I am having a 338 lapua built on a Stiller action,Shilen 28" bbl, Mcmillan a-5 stock......for long range hunting and busting steel. I have not a clue which optic I should put on the gun. I don't care to spend the money, but I was hoping to get something good for around 1400 or so. any suggestions? also what power? thanks!
