My 10T-SR has an Accu-stock with aluminum rail and pillars and I torque it at 40 in-lbs. to get my best results.
I've seen posts that recommend from 45 to 50 in-lbs. for their best results.
That variation might simply be the difference in the torque wrenches - some models are notorious for inaccurate readings.
One key I found to getting accuracy when torqueing is to bring both screws up incrementally to the desired torque setting by adjusting using 5 in-lbs. increments after the bolts get started into the pillars.
Tightening one bolt completely and then tightening the other might cause some issues.
I believe that incremental tightening gets the action to flatten without binding.
