choke constriction
 

I recently acquired an AH Fox 410 by CSM and miked the chokes at .022 & .023. I have no chart to determine if these equate to full, mod etc. If anyone here knows I'd appreciate the info.

Full=.390, ImpMod=.395, Mod=.400, Imp cyl=.405, Cyl=.410.

Rich, Colonial Arms' chart shows .11 as imp. mod.,.015 full and.021 X full. Looks like yours are OMG!

How does it pattern in what diameter circle and at what distances??? That should be a better indicator of effective choke.

Your chokes are very full. Parker 28 gauge full is .020. In a .410, .023 is over the top.

I haven't patterned it but based on what it will do to a target even using the std AA 2 1/2 skeet load I figgured it was very tight. I think these will see a trip to the gunsmith and get opened up considerably.

Don't go too far... you may regret it.

Please tell us a little more about the gun.

John the gun is a recent production (2000) from CSM. It's a Fox FE with straight stock, splinter forarm, double triggers and 28 inch barrels. It has a fairly nice piece of wood and a great checkering pattern. I've included a couple of pictures for you.

Rich ,Beautiful Gun ! I need a nice Side By Side with a Woodcock engraved on her or Gold Inletted ,VERY VERY NICE !!!! Russ
