I have been using PB in my 10 Ga. with the SP 10 wad in the brown federal hulls with no problems, however, when I tried the same combination in the new Cheddite hulls I've had powder seepage around the base of the SP 10 wad. It seems as though I might have to go to Red Dot as the powder granules appear to be larger. I have not yet tried the other wad that was mentioned. Is it slightly wider at the base than the SP 10's?
