Lapping takes out the "Talley Pinch" and other stresses from wonky receiver tops. I can't fathom adding electrical tape to the inside of an already overly tight ring as one mentioned earlier in this thread. That's just adding additional stress.
I bed the bases/screws to the receiver in JB Weld epoxy at 25 in lbs.
Lap Rings.
De-burr and de sharpen any edges with a fine rattail file.
Mount scope in a thin layer of rubber cement.
Blue loctite screws at 20 in lbs.
As I say, at least 25 sets of Talleys this way, no failure. That's not to say they can't fail (obviously they can)...
Thanks for providing this info Brad as I know you have more experience with Kimbers and Tallley UL's than most here. (thumps up mate).
I have pretty much done the same as you have done but I have never used the rubber cement. Might have to try that.
After seeing this thread I was reluctant to use some newly purchased UL Talleys on a 35 whelen I certainly built (Kimber 84L Hunter), but I'm having second thoughts and I may just do it. I have never had a Talley UL fail or one even move in those mounts.
I Have a new VX freedom 2-7x33 lined up in its box, but I am curious about these new VX3HD's Leupolds, so I may wait a bit.
