The 870 gets stiffer as the bolt comes to the rear because at the same time, the bolt is pressing the ejector spring against the wall of the receiver, cocking the hammer, operating the shell lifter, and operating the shell release.

With most everything out, the ejector spring and shell release adds stiffness.

You can help get smoother operation by applying a little grease to the left side and bottom of the bolt, the bottom of the bolt locking lug where it contacts the ramp on the slide, the slide grooves in the receiver, to the front of the hammer face, and the action bars.

Also, compare your 870 to another 870 to determine if possibly something is wrong with yours.
