I misspoke regarding the maker of 'Graf' Brass.

When Graf & Sons began marketing .30-40 Brass, with the 'Graf' headstamp, it was suspected by individuals on several forums that the actual maker was Captech in S.D.

I suppose someone could call Graf & Sons and ask the origin of their Brass?

I am not aware of problems with any brand of .30-40 brass.

BTW - There seems to be a lot of gossip and misinformation on the internet. (I regret when I contribute to it).
