There are different ideas about what constriction constitutes a given choke designation, such as Improved Modified. I like the chart that is on Hallowell's site, which shows Improved Modified in a 12 bore to be .024" to .031". Is yours that tight?

Hi Stanton,

I only have the wedge shaped pocket type choke gauge, no micrometer. Thanks for the reference to the Hallowell choke chart, that is really good information showing the choke size ranges.

I emailed AyA asking about their choke size and steel shot proof. So will see if they respond.
