Fab,
I usually shoot a 425 Ultra XS 20ga in the morning and go back in the afternoon with a 525 12ga or the Dakota 12ga. I like shooting the heavy gun second. The Brownings have 30 inch barrels; the Dakota has 32-inch tubes.
I took the 425 and 525 to South Africa with me in April, on a bird shoot. We did a bit of Duck, Goose, Pigeon, Francolin and Guinea Fowl hunting. We were over for 10 days in the sunflower fields of Free State. Great bird shoot. I took my 28ga and 20ga Citori custom guns to Argentina in June of 05, shot doves with the 28, it was a kick. Went to Mitchell SD in 05 and took my 391 Sporting gold. Prior to that I took my 391 sporting guns to Argentina 04.
We are putting together a little quail outing next month at a preserve in South Alabama. I will take my 1970 vintage 28ga Super Light steel frame gun on that outing. That super light is out of production but a great little mouse gun.
I just started shooting shotgun games in March, and only more than once a month about a month ago. I run in the mid 80s with the 12 and low 80s with the 20. The 1750 round day I had on Pigeons was pretty special....

You can get a 425 so hot it sizzles the oil
After the trips, watching the guns work and not work, I came to love the Browning. In 04 I did not own an OU.
