When you measure a barrel for choke, you are measuring constriction, not choke. Constriction has an effect on choke (the main one) which is defined as the percentage of the shot load striking inside a circle of defined diameter at a defined distance. We hope the constriction reflects choke, because it is easier to determine by measuring the barrel itself, whereas determining choke requires patterning, which requires counting the shot in the load and counting the number of shot pellets striking the board within the circle. With this information, a percentage can be determined. In addition to constriction, the shot size, shot load, charge weight, bore size, protective devices (shot cups, etc) can affect choke. If a premium shotgun is made to order, the customer will typically be asked what choke is desired, with what specific load, and the constriction will be adjusted to give a pattern percentage within the range of that choke. The choke will then be marked. If an economical gun has the choke marked by constriction alone, it may or may not pattern to that percentage. It would be bad to have a "falling out" with a friend or lose a customer over a question choke vs. constriction.

Thanks Mike. That is great info. I appreciate it. All I have is one of those brass gauges from CSMC. And I'll let you in on a little secret. Those things aren't even accurate. This gun's chokes compare with my other 20 gauge guns mark M/F. But I started measuring my other chokes like my Beretta & Browning chokes (even the 12 gauge guns) and some of them are a couple stages off. One of the Beretta chokes marked Modified showed IC with that gauge. On a few of them. But, in the end, the gun was so nice I decided to bring it home. It's going to be babied in a good home in my safe. I appreciated all the remarks. I missed some comments from the people I have on ignore. But, it's like Rosemary Clooney always said, Kay-Sarah, Sarah!! Take care.

I am going to call Cody later on and see if there is any paperwork. Their time zone is a little behind us here in Tree City, Indiana. 👍

Rotflmao! Only DimmyW would post "Kay-Sarah, Sarah" (I can't stop laughing) in place of the correct "Que Sera, Sera", famously done by Doris Day. Boobus Americanus who needs a seeing-eye dog to help with his gun-buying decisions. Too funny...

^^^^^^ I'm sorry, but, I am ignoring you. ^^^^^^^ You have made too many stupid remarks in the past and caused to many problems for others to converse with you anymore. And it isn't fair for the intelligent, decent people on here to take up their time arguing with you and ruining this website for them. But, you have nice day.
