Had no idea the chamber was also hammer forged! Thanks for that information Al.
Not all mfgs. include the partial chamber in the process. Some pull or push the carbide mandrel (that has a short section of rifling on it) along the length of the barrel as it's hammered. Then the chamber is done. Lots of ways for mfgs to accomplish this. If you ever get the chance to see...and hear...the hammer forging process, it's pretty amazing.
