Clay Dot is manufactured to produce the same ballistics as Clays but using a different formulation.
I've built 7/8 oz loads with Remington hulls, DR-XXL 7/8 oz wads , Winchester primers and Clay dot powder from the same formula in the Hodgdon data. At 8,900 PSI it works fine. Or you can substitute the Federal primer for the Winchester and pump up the pressure 1500 PSI. While Clays and Clay Dot may not produce identical ballistics in every case, the variances that exist don't concern me with a 7/8 oz load.
