Guage is the thickness of the stainless steel, or other kind of metal.
The difference between 18 gauge and 22 gauge stainless steel is the thickness. The 18 gauge is 0.050" thick, and the 22 gauge is 0.031" thick. A link is provided below to an article with a list of the conversions. You'll note that the cited thickness for the gauges of stainless do not apply to galvanized steel, aluminum, zinc, brass or other metals.
18 gauge stainless steel is 0.0500 inches thick.
16 gauge is thicker. Remember...the lower the guage the thicker the metal.
.794 mm. (USG)
What gage equals 1/4"?
How thick thick the metal is.
With proper documents and original box and in very good + condition, it is worth about $500 Dollars. My personal opinion it is worth $800 Dollars since they were produced in limited quantities.
The finish of a product would be considered as heavy gauge steel. For instance, an espresso maker could have a heavy gauge stainless steel finish.
Some bolt action shotguns had an adjustable choke, and it is generally NOT recommended that slugs be fired through those. If there is no adjustable choke at the muzzle, your shotgun should be fine. Stay with rifled slugs.
Load, pump, pull trigger. Pump, pull trigger. Continue until all ammumition is fired. Load, pump, pull trigger, etc..
