Stan, Good to hear your progress. I may have some .430 circle fly overshot cards; I'll look this a.m. Don't have wads, though other than plastic. Brass will always have more capacity than plastic as a crimp isn't necessary. I use the RMC recommendation of Duco Cement around the edges of the OSC once it is in place. Over the course of a turkey season, I've not had a problem with the osc card once glued in place. Gil
PS: I use their brass as well as their quality loading kit. Here are the instructions:
