BCCC headstamp


On another forum a guy asked about a 577 NE case headstamped “BCCC”.
I didn’t find any info about this maker , any ideas?


I have that headstamp in a .600 3" NE new empty case & obtained it from the Wells Sport Shop here in Prescott AZ U.S.A. Todd Wells, grandson, of Fred Wells (founder) said he was pretty these were BELL manufacture, obtained when his Grandfather was making a .600 rifle. However I showed my case to Jim Bell a couple of years ago and he sad it was not by him. I’ve yet to find the maker. Jim suggested it might be a European makers product.
Sorry not be be of more help but it sure would be nice to know who made it.
