I got this information second hand but it’s serious enough to pass on to collctors in CA who may want to check it out just to be on the safe side.
Supposedly, there was a shooter in LA (City or County, not sure) that was arrested for possesing some linked ammunition. In the situation that occurred the victim had his entire firearms collection seized and he was told charges are going to be filed because he had in his possession linked ammunition in quantities of more than 10 rounds of ammunition at a time. This has been interpreted as a violation of the “High Capacity Magazine” portion of the Assault Weapons Act in CA.
Again, this may be nothing more than Internet gossip but it’s certainly worth finding out.
