I am sorry for the delay I had a computer crash . I get all my wads from Bucksrun , the data is from Reloaders Specality . I buy my shot form where ever I can get the best deal , this year 5 of us went together and bought 120 lb.
I have found that I save 30 - 50 % depending on the load , 30% on goose loads and 50% on 1 1/8 oz loads for ducks and upland.
