Wayne, using our standards, the 10A brass hull is the same outside diameter as the paper hull. The 10B is smaller. I do not know if European gunmakers did the same thing. There is a bit of a difference between the 'A' and 'B' brass hull. The 'B' will be a loose fit in the 'A' chamber. The 'A' will not fit in a 'B' chamber. All this probably does not apply to your gun. Depending on the gun your 10 gauge hulls were fired in, they will be a little snug, or very snug, when attempting to insert them in a chamber. Try a properly loaded shell and see what happens. Good luck!
