Mr. Hood, as usual (always) is correct. I would increase pull by a few ounces and see what happens. How tight for the rear screw on the bolt rear? Don't go crazy, just use a hex that fits and hand tighten. Each subsequent time you take it to the range, see if it has loosened up. I speak from experience, not knowledge, but experience. As to the action screws, never rely on a previous owner or Savage to have the proper torque. I don't know what it is for your particular rifle, but someone here sure does. If proper torque does not work and the screw is causing the lock up, ask Mr. Hood, who might suggest you grind down the offending screw a bit.
