Larry, where did you find the "even lighter 20's"? They are about the hardest shell to find in a light load. I would reload them to 2 1/2" and roll crimp them, but I have only found a few loads light enough to use. These were 2 3/4" 6 fold, but will work in a 2 1/2" hull roll crimped.
I was referring to guns, not loads. But RST, for one, makes 3/4 oz 20ga loads. So does Fiocchi, I believe. However, thanks to Claybuster's relatively recent release of a very good 3/4 oz 20ga wad, reloading light 20's is a piece of cake. And good hulls are readily available.
