The rounds are reloads. Brass all looks fine. No signs of pressure, primers etc look fine, no cratering/flattening. Bolt opening feels the same as usual, but some rounds are ready for a full-length sizing and a trim before they are loaded again as they are a bit stiff when chambering.
Loading 45.5gr (46 is max according to the book) AR2208 with 168gr Sierra MatchKings - currently shooting superbly out to 500yds. I don't have anymore distance at my range to reach out any further.
