Re: vortex viper 6.5-20x50 vs leupold cds 4.5-14x40
Not tryin to hijack the thread but, i might be able to help...
Elkstalker, if you find lapping doesn't stop your scope from sliding, you may try going with picatinny base(if you don't already have one) and 1.5-2 sets of rings or possibly 1 set with a larger surface/clamping area such as Nightforce, MK4, Burris XTR etc.(lapped as well). The "uber magnums" such as your Weatherby with brakes are very hard on scopes & mounts as during the recoil process as the rifle moves both backwards & forwards. IIRC, Kirby Allen aka FiftyDriver was talking about this in a recent thread, it would be a worth while read.
