As mentioned before, your fired brass looks typical. If you're going to reload, buy yourself a Lee Collet neck sizing die. It will significantly extend case life. Also, your loaded rounds will now be headspaced on the shoulder rather than the rim. Commercial, American made, 303 cases typically have thinner rims than the original milsurp ammo, causing sometimes headspace problems. This is eliminated when neck sizing rather than full length sizing. Good luck with your No1 and enjoy!!
