Konus M-30 scopes are also rated for .50 BMG recoil.
The M-30 8.5-32x52 is what I have on my 700 5R .308, and recently transferred it to my 7mm STW for long range load testing.
Having the Picatinny rail setup on both guns makes swapping simple. Also, keeping a log of what POI for each rifle & caliber makes swapping and re-zeroing VERY quick and simple if you only really have 1 true long range scope.
I have a Zeiss Conquest 6.5-20x50, and it is sitting on my Weatherby Accumark .257 Wby Mag. It is an excellent scope.
The Vortex Viper PST's and Viper HS LR scopes are VERY nice for their price-point, as well. I have been looking at getting an HS LR 6-24x50 XLR (MOA) scope for my STW, for LR hunting, and put the Konus back on the .308...
But I have also been thinking about saving up and just getting a Nighforce NXS 8-32x56 MOAR and putting that on the STW...
Decisions decisions...
But for $899, the Zeiss Conquest 6.5-20x50 would be an excellent choice for you.
Don't worry about the Zeiss not being able to handle the recoil...This is quoted directly off their website...
"ALL Zeiss riflescopes and red-dot sights are rated to the same recoil resistance of 1,500 'g's at 1 millisecond. This is about 4x the recoil of a .460 Weatherby Magnum. They will also handle the reverse recoil cycles of rifles with muzzle brakes as well as that of airguns."
