Hi I am a new member and have been studying all the information on this site about evaluating used guns for safety. I have just acquired a 20ga AYA #3 manufactured in 1983. The gun is proof marked at 1000 Kp/cm2. The bores measure exactly as marked at 15.9mm and the chambers measure a normal size per CIP tables, the chokes seem original. The barrel wall thickness of the thinnest barrel measures 0.065” at the end of the chamber, 0.065” at the end of the forcing cone and 0.043” at 9” from the breech. The original barrel weight was marked at 1080 grams. I’ve weighed the barrels and they are currently 1067 grams. I’m baffled were the 13 grams of material went.

I’m wondering if I should be concerned at all or just use the gun and enjoy it. Thanks for any advice.

Welcome on your first posting

Initial weight, some work need to install and contour
Should stay within 98% of the stamped weight

Use it and enjoy it

Salut,
L'épaisseur des tubes son dans son dans les clous de la CIP.

Perfect!!!
Those are the numbers I remember.

Thanks.
