Re: Action truing/blueprinting
If you watch the videos, it clearly shows that nothing is square or straight about any feature. How much out of square is the question... The receiver threads are generally tapered, since Remington cuts them with a tap, vs single point turned on custom actions. Typically also off center.
Remington is flat out making the receivers and bolts using worn out and outdated equipment. They chamber barrels in a vertical mill. No lathe, no dialing in the bore. Nope, clamp it in the fixture and down comes the spindle of the mill... With the cost of modern CNC equipment, they could pitch all of that junk in a heap and be making custom quality receivers much cheaper than the existing guys since Remington has so much volume. I'm pretty sure that all their sniper contracts are re-worked in the back room and they fit aftermarket match barrels or else they would never pass the requirements.
