Brass deformation???

GT, I helped a similar problem my Stainless Houston Luger displayed. The rims of the ejected brass all had a triangular "karate chop" mark, along with a slight burr raised by its striking the corners of the slots inside the barrel extension. I marked the rounds to index them and discovered that the shells were striking the left side.

I removed the extractor body for closer examination and noticed that its claw was not symmetrical, and a little longer on its left side. I went easy with a needle file and evened them up a bit. Although this seemed to steer the situation in the right direction, I quit filing as soon as most of the cases made it out unscathed, or with perhaps only a mark small enough to be ironed out during reloading. Replacement stainless steel extractors are in the same category as hens' teeth, as you know!

I, also, am interested in this thread. My like new 06-73 Mauser Parabellum is really quite rough on the ejected brass. I can't see anything causing it, but apparently it is quite common on these Lugers. This characteristic has not lead to any feeding inconsistencies, but I do not own a drum mag....old or new. Some of the spent brass is so dented that I just toss it, and that is tough to do for a handloader.
