Thank you Dave!!!
Unfortunately geese hunting is not authorized in Italy, although geese are lots and lots in the last years and numbers are increasing year after year.
I bought n.7 (diameter 2.5 mm) because it seemed to me so thin... but I have 2.00 and 2.25 too.

So I shot shot 2 with the 37grns lil gun and all steel no tss and the wads were torn a bit but not as bad as with the tss and all the filler wads. For testing I loaded up 3 rounds with 36grns powder 120grns #7tss and 300grns #2 steel. This only needed 2 filler wads under the shot. Book speed on this one is 1400fps, vs the 1460 for the 37grn load. I will see what the patterns and wads look like.

So I did some testing this weekend. I am going to put the 20 gauge on hold as the lee load all will not make a decent crimp no matter what. I have tried target loads, different hulls all with less than great success. I have ordered the tooling for the P&W so will wait for that. On the BPI 20 gauge load I am getting the brass torn by the extractors and ruining the hull. This happens even when I drop to 36 grains. Anyone have this issue with Cheddite hulls? It did not happen with factory target loads.

On to 12g, I did a mix of 9 (100gr) and 7 (75gr)TSS with #2 steel (260gr). This filled the wad nicely with only one felt spacer. I was happy with the pattern on this one. I will do some more pattern testing and if they continue to look ok will most likely make these our duck/goose load this year.
