I used the number 2 method for many many set ups for many many years and never had an issue. I use a Fat wrench these days but I wonder just how accurate it really is. I never had any issues with the scopes I mounted using the fat wrench but for no real reason I am suspicious of just how accurate it is.I wouldn't use Talley ringmounts myself. I had them crack. But if you are wanting to keep them, here are some thoughts.
I've used #2 above on literally dozens of scopes and rifles. No slippage or anything weird. As long as you use that short end you are unlikely to damage anything.
- How are you measuring torque? Sure you are getting a valid reading?
- Either way, try taking the small L-shaped key included with the rings, and hold the short end and see if you can snug the fasteners. Once that's done, I usually flip the key around and snug a tiny bit more but choke up on it.
Be careful cranking away if you don't know the quality of the torque tool!
