True Story
Back in the day, I bought a used Pump Gun for a beater, a loaner a...it was shoved into my hand as I was drinking the gun shops coffee, I still think they did that to keep me from snagging another cinammon twist...
The gun needed some attention, as the wood and and blue was great, the barrel needed tweaking to shoot consistent patterns.
First thing I had the guy do was remove the marking on the barrel stating what that fixed choked barrel "said it was".
Folks get a "choke marking" in their brain, on barrels the first thing anyone did was "read" the barrel marking.
I visited with the gunsmith guy , who grinning ear to ear, and especially after I said I wanted the marking gone. Everthing else from Mfg, city and state, to 2 3/4 " only shells to , all ususal markings - except no barrel designation.
He did the work, as I wanted, and we conferred on, gun tested along the way and I worked up loads.
Dove hunting , loan the gun with the loads for doves it shot best and folks felled doves, I mean they felled doves and wanted to buy that gun.
"Not for sale"
"What barrel is this, what is it 'choked' ?"
What do you want it to be ? " I would ask.
"IC"
"Then IC it is"
Repeat with different shooters and that gun was anything from Open Bore to Extra Full. Whatever they wanted it to be , I replied "it was".
I did the same thing on Ducks in flooded timber to Geese in fields to rabbit hunting to squirrel hunting to shooting slugs at deer to busting 25/25 on a skeet field to...
NO screw in chokes remember, no barrel marking either. I would loan the shotgun with the loads for the critter.
Gunsmith died , but for years upon years we laughed about this. Yes there were a few more of these guns done, either for me or very close friends of mine whom thought as I did and no I will never share what that gun is, or what the heck we did.
Oh, I did this on more than one brand and action type .
Guns is/are still shooting, and whatever choke you want it to be "it is".
I am not bad - just consistent.
