I did my first rebarrel of a rifle and made it a 25 creed. I have only been reloading for about the past 2 months after slowly acquiring the necessary equipment. I keep running into pressure issues it seems at lower velocity then others. I have been using N555 the last 2 times out. 40gr at coal 2.738 using 127 hammer bulletsat 2710fps. With this bullet I hit lands at 2.749 from what I measure. Although box hornady load fine and they are 2.800 anyways. At 40 gr of 555 I start seeing markings on the brass. Is this something to worry about or do I need to back off? It looks like the ejector is striking I have many more questions but only because I have nobody to ask. Haha
