If I were you Terry, I would try, as Huntsman suggests, the Winchester Super X foster slugs. I have played with many smoothbore slugguns over the years, and have almost always gotten my best results with Winchester slugs. In addition, since you have a 20 gauge, the Winchester slug, at 3/4 OZ., versus a Remington slugger, at 5/8 OZ., will hit harder. My daughter shoots a Pre 77 Remington 1100 20 gauge. With a smoothbore slug barrel, and a Bushnell Banner 1.5X4.5 scope mounted in a weaver converta-mount, it will shoot SUB 4 inch groups at 100 yards with Winchester slugs so consistently it's monotonous.
I remember the Ithaca 66 Supersingle well, I had one in 12 gauge in the early 70's. I think the biggest problem you will encounter with that gun, is the ability to install some type of ridgidly mounted iron sights, or scope. As I recall, the action only has a very small and short rib on top, and is not drilled or tapped or grooved for any type scope or iron sight installation, and without some type of rigidly mounted adjustable sights, be it either a scope, or iron sights, it will be difficult to get any kind of consistent grouping with any brand slug, let alone be able to compare results of one brand versus another. Good luck.
