I got a idea......

In years past I did a LOT of shooting with the foster type slug from a 12 gauge smooth bore and got good accuracy from slightly modified Rem. 870's and tinkered factory foster slugs.
The better guns/slug combo's would hold 3" sometimes a tad better at 100 yards.
Wonder if there is a foster mold available to cast foster type .20 gauge slugs?
I've found that Lyman makes a sabot type slug in .20 gauge, but i doubt the design would work in a smooth bore. The wasp waisted sabot design slug REQUIRES a rifled barrel to stabilize it. I tried the then new sabot slugs in smooth bores with dismal to worse results. Even at 25 yards the sabot in a smooth bore would keyhole. They would not stabilize at all at any range.
If the foster slug is available in .20 gauge it might make the .62 smoothie a real kick butt load.
Whaddayathink?

What about drag stabilizing. Drill a small hole in the base of the wasp-waist slug, insert a 12 inch piece of strong string and peen it in place. A knot on the end of the string should give enough drag. Insert on top of a shotgun wad. As a bonus it would be easy to recover the slug from a deer, just pull on the string. ::

I used this technique when I was a boy. I had a 300 gram sharpend steel bolt on a two meter string which I would swirl over my head and launch lengthwise over a soccer field. I almost made the distance several times and it always struck point first. It dawned on me how dangerous this weapon was when it went through the hood of a car in the parking lot. Needless to say, I ran like the devil was biting at my heels. I've always wondered what that car owner thought when he saw that steel bolt embedded in his hood.

It is for Ballistic Products. They have foster molds for the 20 ga. They also carry many different types of slugs.
