I am having a 7mm RUM built, not quite sure of all the specifics yet, but curious as to what you suggest for a good scope.! (please lets save the "Go 30 Caliber" talk for later, as when the time comes i'll get one, but right now is the time for a 7) My hope is to have a gun that I can kill deer and antilope with at 800 yards, and a scope to help in every way possible. Are there any scopes that have adjustable BDC's? Red field did make some 7 mag scopes with cartrige changes for different bullet drops but I have had a hard time getting a straight answer since they became a leupold company. Thanks for the help!! Budget - $300 would be great but if $600 has to be done than so be it, but probly cant do much more than that.
