Right, wrong, or indifferent, people are using the terms watertable and monoblock to describe the flats of barrels and action and to describe "sleeving".

A look at the Simmons Gun pricing list will reveal "watertable" in there when referring to engine turning (another term of contention? anyone? crazy) I have heard a number of older shooters refer to what Simmons did to make subgauge barrels for O/U guns in the past as "monoblocking". The group of other older shooters always seemed to understand the term. But there was no "gun terminology police" to tell them they were wrong. grin

Someone called my papered Lab a mutt. I have all kinds of pedigree documentation and a DNA registration on the dog saying it's a Lab. Is it still a mutt? Probably. All dog breeds are crossbred if you go back far enough to the wolf.
