Stan,
No. I have met a total of one guy with a choke tube holster and the speed wrench to change choke tubes while he was shooting. It never used to be this way, but, my club is actully packed with high school kids who shoot on their trap and skeet leagues, and observing them, and the rest of us oldsters, "few" actually mess with the tubes in their guns.
I never said "nobody" Stan, you did.
Have a drink Stan. Have a cigar in the gunroom, if that is what you do. Do what makes Stan happy on a Saturday night. If you are surrounded by guys who change their chokes tubes persistantly, be thankful for the company on the range, and enjoy your shooting.
And, have a blessed holiday season, Stan.
Best,
Ted
