Reloading 12 ga. Sabots

Does anyone reload sabot slugs? At $10-$15 a box for the premium sabots, is it realistic to reload them? Alot of counties around here are shotgun only, but allow slugs. I have two rifled 12 ga. dedicated slug guns, but they are pricey to shoot. I reload for all my centerfire rifles, I was just wondering what it would take to reload sabot slugs.

Any info much appreciated. [8D]
