Brent, odd that your 25" Ithaca SKB is missing the RayBar sight. Came on all of the guns imported by Ithaca. Might be someone (like you) didn't like it. But maybe it'd shoot straighter if it were still there.
Seriously, I'd sell that gun you can't shoot, if I were you--unless you determine it shoots so far off that you'd be cheating the buyer. Considering the gun seems to be that far off for you, you might want to consider shooting from a rest (a bag of shot or something on a portable table), like you'd zero in a rifle. If it's off that way, you know it's REALLY off, and the problem is the gun and not you and how you're shooting it.
