10 ga choke?
OK, I have a PH 10 ga twist barrels. Looking for help with what the chokes are. Micrometer at the bore is .739.
I don't have access to a bore gauge to see what all the numbers are. Does anyone know what the choke is just based on the end bore constriction number?
Gun looks to be unmolested/messed with.
Thanks for any advise.
