Mainly wanted to mention this useful site on Headstamp Info. It happened today to be an ideal source as I was puzzled over one headstamp on my .223 once-fired cases.
Turns out this was BlackHills Ammo. Lucked out a bit as on going thru some bulk stock of once-fired and deprimed stuff .. turned out a large proportion was this match stuff Nice brass, altho some has small ejection dings but that will fireform out when used in rifle or Contender. I do like to have same brass for more critical loadings.
Used some of that usefully restocking my varmint loadings .... and while these are lethal lil fellas - there is some sense of eye candy as well Hornady V-VAX 60 grainers over 3031. Only a quickie pic so bullets look a tad dark.
