Lapua, adg, and Peterson all need to be prepped as well.Your the lucky one, 5 of mine had dented in necks. I was told you have to size them, chamfer them and trim them anyway before you can load them, but it was still new quality brass from Lazzeroni. My definition of quality brass is usually annealed,properly sized to sammi specs and ready to load, some are even already chamfered. I guess I’m used to ADG, Peterson, or Lapua brass, only I don’t have any of those options for Lazzeroni unprimed brass. Now I know why people sell their Sako M995 Lazzeroni warbirds so cheap. But it still shoots well. When I get tired of it I’ll just rebarrel it to a different caliber. It’s already been restocked with a nice custom thumbhole stock and I like the smooth action. Stay safe and enjoy the great outdoors.
