Reproduction 28ga tight chokes
 

I just checked my screw in chokes in my 28ga Classic Doubles o/u. They were made in the same factory as the Parker Reproductions. They seem to be just as over choked. Full - .039 , Mod - .019 , I/C - .009 - SK - .005 ( larger than bore). Skeet choke was larger than bore. So .014 difference between IC and Skeet. I guess no one at the factory knew how to choke a 28ga.

Makes me wonder about the chokes in my Dickinson Estate 28 ga--I used the cyl and IC chokes grouse hunting last year to good effect, so guess I wont worry about it.
When does your New York grouse season start?

Harold, it opens September 20 in Northern N.Y. , I plan on being there, just hope some grouse are also.
