A vendor at a gun show had a barrel for sale, marked as Stevens (factory markings). My question pertains the threads--they had flat tops rather than sharp. Very uniform, full circumference and length. Is this normal? Stevens and Savage? It looked nothing like the LW that I had bought earlier that day. Obviously, I've yet to see a Savage factory barrel off of an action--yet. Thanks, Steve
I am pretty new to these barrels as well, but the four I have been around the last month or so are all as you describe.

I have barrels with very sharp threads to very flat topped threads and the major diameters range from 1.061 down to 1.045. all of them work fine. I have not verified it yet but I suspect that the minor diameters of all the barrels are very close to each other.

My factory LRPV threads a sort of flat on top. Also a prefit Shilen barrel came with flat threads also. I think its good in some ways (no gauling problems) and bad in others Too much wobble (leaving the nut to do alot of extra work).
Flat tops on the threads have nothing to do with the pitch diameter. The pitch diameter is where the threads engage each other. So do not worry they still should be a nice fit.

Dinosdeuce must know something about machining. ;)
