    I reload .308 for my DPMS & have noticed that on all my spent cartridges I get a small indentation about midway up the cartridge. It's probably about 4-5mm in leangth. Even on loads as low as 38.4g I see it there. I use Winchester cartridges & IMR 4895 powder. Should I be concerned? Any thoughts would be appreciated.

    Thx

    They are likely from the case hitting the ejection port.
