I do not know the rifling twist on your barrel, but it is common that slower twist barrels stabilize the bigger bore size slugs better. A faster twist barrel will stabilize the newer fancier ballistic tip slugs that are actually smaller diameter better. I know you said you tried a variety of ammo, but if you only tried the newer fancier ballistic tip type slugs, you aren't really trying the biggest variety of slugs out there. You should go get some of those gigantic Brenneke slugs and see if those shoot any better. If you already tried this kind of giant bored slug, well then, I would just zero it at 100 yards and accept the fact that at 50 yards you might be a little off. Better to be off a little up close than a few more inches at 100.

I'm not surprised at all that you're hittling on at 50 but 4-5 inches to the right at 100 yds with iron sights.
I would adjust the windage by moving the rear sight slightly to the left. Brace the gun firmly in a vise with some padding. Apply a strip of tape to the barrel, and another on the sight, close enough to each other so you can draw a line along the barrel across both pieces. That way, when you drift the base in the dovetail, you can tell how much you have move the sight. A minor adjustment is all that's needed.
