I do. I use the 2092 wad, put the mylar in the wad followed by a cork and 2 felt wads.
you are talking about the Big20 XL.
The Big20 Stubby XL load uses a Federal hull, does not use the VP2092 wad, no Mylar, and other different components. Not posting any more than that in order to keep Hal’s info from getting to China lol.
