Old browning shotgun choke id

I say test with what you plan to use.
I patterned one using five different 00 bucks. The results were shocking. Some brands and types spread so wildly you could not hit a VW at 30 yds and some brands shot very impressive tight patterns. It is a LOT more about the actual shells sometimes than the choke. The chokes vary so much then add in the shells vary wildly and you get surprised .
Go to the Dollar store buy some cheapo poster board from school supply section , go test. Surprises are a sure bet

243winxb has got it right! I bought my Browning 12 ga. Light 12 in jan. 1969 and the hand book lists 2 stars as modified choke----that is what mine is.

P.S. Had to buy a new barrel (Jap) when I started waterfowl hunting as the steel shot was too hard for the barrel steel of the original barrel. Jap barrel fit perfect-liked the choke tubes also!

This was my dad's old browning 12 gauge automatic he left to me a long time ago. Great shape.I just don't have any info on it.And cannot figure out what it is on the browning Website.
I am trying to figure out what choke it has.
It is a fixed choke , but not sure what .
Id love to use it with 00buck

If a dime will not go in it,s a full choke.
