Agreed - excellent indeed!

#2 or #3 shot would be a great goose load, if in lead.
old saying:

"less powder, more lead, shoots far, kills dead"

This worked well in my "Field London" 12 bore BP loads SxS, second in trap, shooting against a hammered, single shot choked gun (a bunch of those in the match).

Used 2 3/4 dram load with 1 1/4oz. shot. Smoked most of them. Had one more miss (easy shot too but missed) than the winner.

I am not suggesting you use this load, but the basic concept.
