its interesting reading the posts.. the double nitro card load is the standard vm starr method and he won a contest blasting 400 crows in one season or somesuch with it.. theover powder card/ wad and lube is what i use and its seems to work best for me..i use tc yhellow lube in the tube, a large glob evenly between the card and 1/2 inch fiber wad in cylender bore gun.. dont know why, but as the temp gets cold the fouling gets rock hard below zero and blows patterns for me.. could be the size (diameter) of the cards and thier hardness or somesuch.. i used to use powder/nitro card and shot/overshot card for quick load for swatting ducks and it would ruin patterns for some time after.. so i guess it depends on your other things your doing out there, type of gun, weather, kind of powder etc etc.. my best recomendation is to get some 30 inch paper and pattern until you get the hang of what your doing.. a couple years later with many many patterns, and after a thousand or two clay pidgeons you may start to get the idea of what your gun wants, and what it will take to tackel a pheasant or duck with some regularity.. dave.
