Hey guys, I have just picked up a Weatherby Mark V in 300 Weatherby Mag for a very good price with 80 rds of ammo. I need to put a new scope on it and I have a very limited budget ($300). I currently have a Burris 3x9x40 Fullfield II on it now, I'm looking for something that will be good to 400+ yards. Any suggestions? TIA
