OK, I'm not the brightest person, but I have a 783, 16" semi heavy barrel. It has never bound up and shoots excellent for a cheap factory rifle. I torqued the plastic stock to factory specs and the only problem (which is common) is that the rear screw pulled through the cheap plastic trigger guard. So, I got sick of that stock and bought an original Remington stock (surely made by Boyds) off Ebay for $70 and bedded it. Since the rear screw had pulled through the trigger guard, I fixed that by drilling out the hole and gluing a bushing inside, which sits on top of a flat washer in the stock. That fixed the trigger guard problem because it is no longer used as a washer. Hey, I'll be the first to admit I am not a stock expert, but I can shoot the rifle now.
The baffling part for me is the mention of a middle screw, but mine is a short wood screw that would pull out of the wood before it exerted any pressure to the action.
But my experience with the trigger guard tells me that too much torque will smash the cheap plastic trigger guard that is acting as a washer so that it is thinner than when it was new. If the rear trigger guard screw is over tightened and crushes the trigger guard, the rear screw can protrude in the bolt raceway and bind the bolt. I know this because I had that happen when I was fitting my bushing and washer setup. That, to me, is more logical than warping the action.
Now, if someone can find a cheap replacement trigger guard made out of metal, it will feel like Christmas to me. Until then, I am seriously considering
