[quote=sxsman1]I have used the Gualandi wads with terrible results.

I'm curious about the problem that you encountered with the SG16 wad, because I have found it to be excellent in straight walled hulls.
Claybuster 16 gauge wads have the smallest diameter skirt, which leads to powder migration and bloopers, in cartridges carried around in the field.
It's hard to find a straight willow on the Prairie, when you have a stuck wad, a long way from the vehicle.
