I bought a 10 gauge online years ago from a guy that confirmed that it was a browned Pedersoli...well my Pedersoli looks a lot like a blued Pietta. But at least it was a 10 gauge. I have hunted with that gun for many many years. Great Water Fowl gun, not much fun to lug around on a pheasant hunt or dove hunt.
As for Steel Shot, I bought a nice supply of “T” shot and #4 from a local supplier before the industry took that big hit during the last election cycle. I hope things start to settle soon and components are available once again.
I have used that gun to harvest more geese than I care to count. What an awesome goose gun. The guys didn't much care for it...I had to take the down-wind position in the blind or they couldn't see jack after I shot.
Here's my loads:
Goose Hunting: 1st shot of the day, clean barrels: 100 grains ffg, over powder card, fibre wad (Soaked in Moose Milk), 96 steel "T" shot inside a 10 gauge wad, over shot card. For following shots I back off to 90 grains of 2 ffg and still get about 1580 fps. After years of goose hunting I have come to the conclusion that with steel shot...1500 fps is the magic number. Faster is even better. But once you see that landing gear...its time to bang away.
Duck Hunting: 80 grains ffg, over powder card, same measure loaded with #4 steel shot, over shot card. Nice load...you can shoot it all day and I don't have any fowling problems if I run patch about every 10 shots or so...The first shot should be taken at ducks that are no farther than 30 yards or so. After the first shot fouling provides a nice jump in velocity with successive shots and it has a better punch when it connects with ducks that are laying up at 40 to 45 yards.
Small Game, Dove, Squirrel, Rabbit etc: 60 grains ffg, over powder card, same measure loaded with 8 shot or 7 1/2 or 6 shot, over shot card. Nice easy load. I don't shoot it with this load much anymore...I have a beatiful Pedersoli 12 gauge upland that is just made for light carry and light loads.
