I use Talley LWs exclusively on all my rifles, including my 300Rum, although it does have a brake on it.
Haven't had one fail.
I do torque to their specs, and make sure the ring screws are evenly torqued, and the gap between both screws and both sides of the rings are as close to being the same as I can eyeball.
That would tend to make sure the stress is as evenly distributed as you can make it. I also torque alternate side screws, like you do car wheels. I work with mechanical engineers, and I know the importance of proper torque techniques. That being said, I've seen mil grade equipment, using mil grade alloys crack due to improper torque and/or over stressing . So the bottom line is even the best alloys can fail ....
Also, after I mount the base part, I place the scope in the bases, and slide it back and forth to make sure it does so freely without binding. Haven't had one that wouldn't allow the scope the easily slide.
But, I do inspect my rifles prior to using them. Schiit happens .....
