land and groove ?

[PJ]

Guys,
If you look at a barrel lands and grooves. Is there anyway to tell how it was made? i.e. button,cut,hammer forged, whatever?

Probably not,without knowing the manufacturer, as most barrels,that I know of)are lapped after they're rifled.

It's easy to tell the difference between a hand lapped barrel and a factory one because the customs are hand lapped. Once this has been done, I don't think you could tell a cut barrel from a button barrel with a borescope. I haven't handled all that many blanks but if it weren't for the stamp on the end of the shank, I wouldnt be able to tell if it was a Kreiger or a Shilen.

Tightneck is right,I meant match grade barrels,not factory.
