I have a White Lightning 28" from a few years ago. I like it a lot, it is my primary bird gun.
One odd thing about the Browning choke tubes that I found out after buying a good barrel gauge - the tube I have that is marked " skeet" has between 1 and 2 thousandths of an inch more restriction than the one marked IC. The full choke is ridiculous - so tight I can't get it to pattern with any normal load. I have used the IC/Modified tubes to kill a lot of game.
When I compare mine with a 20 ga. Citori it looks like the frame is nearly identical with a few minor modifications. It handles like a 20, kills like a 12, just like a 16 should!
