I load with little else because a lot of clay grounds in England, and game shoots, insist on bio-degradeable wads. Most of my loading is with components easily sounced in the U.K. but I do have some information for Hercules/Alliant powders and CCI & Winchester primers. Most loads just require a slight powder increase with the use of fibre wads; usually 1 to 1 1/2 grains extra. If you use the same load and just substitute a card and fibre wad you will certainly be on the safe side. Try that then just increase the powder load by 1/2 grain increments but do not exceed 1 1/2 grains over standard. Lagopus.....
