I own a Win 1300 20 gauge. Love the gun. Patterns fine with just about any shot I've bothered to try. Slugs are another manner. I simply cannot get this gun to group shots. At a measured 50 yards the "pattern" with Win Super X foster type slugs is in feet not inches. I've tried an expensive set of adjustable (windage and elevation) front and rear sights that clamped onto the rib. I ran out of elevation adjustment before I could see if it grouped worth a hoot. I don't need a rifled bore and sabots. I shoot slugs at bow hunting ranges. I strongly prefer 20 gauge for all my shotgun shooting needs. It has worked well except for this. I had an NEF that would shoot slugs fine but alas I sold it hoping to get this Win to work. If I can figure this out it would be the perfect gun for my needs. Any tips or ideas. I also cannot find a rifled 20 gauge slug barrel ANYWHERE! So that's out.
