After that awesome display of accuracy, I made a change on the action screws from snug to 'oh yeah, thats tight'. The groups changed, but still lack acceptable accuracy from a $1100 rifle.
If your accuracy changes with torque changes, it's a sign of poor bedding.
Bedding: None. I've waited on this, wondering if this one needs a new barrel before I spend the money on bedding.
You've got this backwards. You should
definitely bed the stock before you do anything else. A new barrel should be a last resort after you've eliminated everything else.
