I've also found that once you have torqued everything down to the instructions above go out and shoot it and then re-torque. Check this torque value after every shooting session till the torque stays the same. Once you know everything has settled you're set. I read somewhere about fine tuning this torque value and it works great. By loosening the rear screw, I have a 10fcp-k with the rear screw under the bolt release, then setting torque to 20in-lbs and shoot a 5shoot group with your most accurate load...then increase the torque in 5in-lb settings shooting 5 shot groups..up to 45in-lbs. I diffidently saw my groups tighten up around 30in-lb where I keep it.
