I use .002 in Briley light weights for skeet. The patter is great at skeet range (22 yards), 30 inches and uniform and full!

My Dickinson Estate .410 has factory marked M/M fixed chokes that measure .009/.009 with a dial caliper.

Interpretations of .410 full choke constriction seem to vary widely. Winchester had .017 in my M42s. My Ithaca ICD has .020. My Ugartechea had .025. A friend's 2 Perazzi guns had .036-.037.
I have a gun a previous owner opened the chokes to .000 and .010. I shot a lot of birds out pretty far with that cylinder bore. I believe the fact that I have very long forcing cones in that gun contributes greatly to the tight patterns.

Less choke = better patterns. The less crush inflicted on the shot string the fewer flyers, we polished forceing cones on 410 tubes and increased the BB count in a 30 inch circle by 25 and the percent by 15%

Stan mine is fixed mod/mod as indicated by the 3 stars on each barrel forward of the flats. Works well for me.  Adam

Hi Adam,
I was wondering where you had been. Thanks, I hadn't read the manual and had not noticed the stars. I'll see what mine has, but I'll bet it's got three stars, too.

Chuck and Bill,
I have two guns on which I'd like to lengthen the cones and polish them, but they are both chrome lined, and I just hate messing with them. Have either of you ever cut any that were chrome lined?

Stan, I have not. But a high speed steel reamer will get trashed cutting it. A sharp HSS reamer that has been TiN coated should cut it. TiN is harder than chrome. My 3" forcing cone reamer is simply a regular #8, 1/4" per ft taper pin reamer, with the forward chamber diameter O.D. ground (no clearance) on it. Something like this. https://www.mscdirect.com/product/details/02402089 A custom cutter grinder should have a source ti TiN coat. Carbide would just be expensive as hell.

Chuck,
I just emailed Mike Orlen with that question. I will post his reply when I receive it.
Thanks, SRH
