I'm not at all familiar with CETME's, but would this change be enough to trip someone's suspicion button?To me it sounds a little like screwing a fake can onto the barrel. Why???
To be completely fair and open it must be noted:ApacheCoTodd,
That's really strange. I never realized that anyone would think that having LC brass was illegal. Granted, you're talking about California, but still. LC brass is incredibly common, so the field interrogation because of your use of it seems entirely bizarre to me.
I'm in law enforcement, and I think I'd have been even less polite with some idiot accusing me of unlawful activity because of my use of that brass. You can buy ammo at Cabelas loaded in LC brass!
