I have a 300 RUM. I had a problem with scope mount on this high recoil rifle. The Leupold standard mounting base (Az adjustment on rear ring and dove tale front ring) loosened up and caused me to lose scope zero. At first I thought the scope was bad since I had indeed lost a scope on this rifle, previously. The first time the scope was sent to Leupold and after a quick turn around they stated that the scope was indded bad and was repaired. This second time the scope went to Leupold and they stated that the scope was OK but they did diassemble, readjust and completely check out the scope during reassembly (that Leupold warranty on their scopes is great). I did find the scope mount screws were also loose when the problem became evident at the range and I did tighten them. Still having what appeared to be scope poroblems, I sent the scope back to Leupold.
I bought a set of Warne scope mount hardware. The single piece base with four mounting screws and the Weaver style rings with the inserts in them. I mounted the base and installed the rings (It seemed like a piece of cake since no adjustment was evident to me). Well, when I installed the scope and try to boresight it, I ran out of scope adjustment in both in elevation and azimuth before Ireached the zero point on my boresight collimater. Is there something, I'm not doing properly? Is there a way of adjusting the rings when installing them?
Thanks for your help.
