Thanks all.
I've found RC4 high speed number 2 shots shells at my gunsmith, they just reach the 3.5 mm legal limitation, but aren't nickel plated, so I'm not supposed
to use them close to water. Unfortunately, I should not use those 1370 bars shells in my usual field gun, I'd have to take my Browning ultra.
I know the patterns of my field gun, it is not ideal for waterfowl but as pheasants, woodcocks & hares, ... are our main goals, I use to favor that gun (and he can shoot slugs very good up to 35 yards, which is very useful in cas we'd meet roe deers or boars). By the way, that old gun can clean kill rocket roosters at 50 yards with simple number 6 pellets in the cyl. barrel. When I used it on geese, we clearly eared the smack of the pellets on the feathers, so I believe I was on my targets and the gear failed.
I'll try to make some special geese hunt with the ultra XS.
