I have an Eastern Arms Co. 20 ga. that does not have any markings for what choke it has. What are the measurements to see what choke it is? I do have access to micrometers to do the measuring.Thanks Phil
Thanks onpoint. This way it will help in choosing the right shot to use with it. I had gone by the choke to get the right shot and velocity to pattern right for me. And not knowing what it was,bugged me because I was having trouble getting the right shot.
