Hello guys,
hope everyone is in good health, or at least as good as you were a couple of months ago.
I have always wondered how long it takes to really & properly measure say a 30"set of bbls for wall thickness. Do you go round n round slowly advancing up the bore, or what?...it seems like it could take quite a while, as you wouldn't want to miss a thin spot. I guess getting closer to the muzzles, you can speed up a bit?
I have no idea, & would like to know.
Cheers lads.
