Put a Remington Super Full Turkey Choke on my 12g 870 express and some TruGlo fiber optic sights then took it out in the back yard to check patterns/sight it in.

First shot, 25 yards away, looked like somebody had thrown a fragmenting baseball (if that makes sense) at the paper that hit exactly where I had aimed.

I backed up to 35 yards, took a shot, and then only needed to adjust for less than an inch of windage (the first shot must have had some error in it). I then took three more shots and all three were very acceptable.

I never would've imagined that I would just wind up landing it dang near perfect when I installed the sights haha.
