What'd this shiny spot on this piece of brass? I've never seen this before. Is this a pressure sign. This is out of a 6.5 cm. 143 eldx hornady brass 40.5gr. Of h-4350. I had very slight ejector marks but I didn't think the pressure should be very high here. I shot 41 and 41.5 gr and the ejector marks were gone as well as this shoulder mark. Also, yes all the 40.5 gr rnds had the shoulder mark. Some more then.the others. Thanks
