Help - Wall Thickness at the Muzzle ?

[oskar]

Don't know what these measure but they are factory original. Right barrel is a reverse choke. Notice the reamer marks.

I normally shoot low pressure 7/8 oz loads in this gun but wouldn't hesitate to shoot some 1 ozers. Mike

"This is why we adopt our policy on wall thickness , in order as practical gunmakers to give you , our customers , good service and peace of mind "

good service and piece of mind... hopefully, this is a goal of all double gun sellers.

.025 may be ok for the british, where pressures are typically less than what we experience; but, that is why i like .030 as a minimum standard for fluid steel barrels. and even more for twist and damascus barrels... better safe, than sorry.

For my part, the Gibbs standard as presented is beyond reproach. And I'm sure the professional barrelmakers whom I know would agree.

Of course, anyone is free to adopt their own yardstick. With any rationale they care to apply.

Best, Kensal
