IME The factory stock is fine with the following changes:
1. Pull off the recoil pad and glue it on
2. Free float the barrel from the action forward
3. Glass bed a 1/2" hardwood dowel in the foreend to stiffen it up.
4. Glass bed the action and, insofar as the recoil lug goes, insure ONLY the rear of the recoil lug is touching anything.
5. Torque the front action screw to 65 ft ins, the rear to 35.
6. Adjust the trigger as low as it will go (about 2.5 pounds)
After doing this my 270 XLC went from 2" groups to this:(5 shots freshly cleaned barrel)
