Hey Rick, I was looking at my chamber on the feed end portion of the barrel. Im new to this and just outta curiosity the attched drawing I drew shows a radius in the barrel that I was curious if was common on the 30 caliber lugers. wasnt tottaly sure of how the geometry of this inside of the barrel looked. Just learning as I go here. Knowledge is a wonderful thing. I have learned so much just reading thru threads on this web sight.
Thanks
Glenn
