Another newspaper cutting from about 1900 which illustrates very well the use of choke in a shotgun. Particularly relevant to me a month ago when I was trying to find a good visual method for the new TEAGUE Precision Chokes website we were doing at the time and found last night when too late!
I even discussed with the English gun author and gun critic for The Field, Mike Yardley, resurrecting these old tests that were done on guns to judge performance.
