i would think the first shot from an 8 gauge would take care of the snow on the pattern board
as for your math- agreed- as long as you have two of the variables - you had wall thickness and outside radius, you can get the third.
Before I acquired my gauges I bought a gun I wanted the wall thickness of. I borrowed a bore gauge, measured the outside and did the math. Later when I assembled my set of gauges I repeated the exercise and then measured the walls- the numbers agreed. just don't tell the late Mrs Peterson I actually used the math she taught me in school - the shock would kill her again.
