I wondered about the Ca content of "Calcium" pills myself (the kind I take
don't have Mg).  So I weighed the contents of a bottle of 120 of the 600 mg
pills, and determined that each pill weighs about 1.8 g or 1800 mg.  If they
do contain 600 mg Ca, which is 40% of the CaCO3, then the CaCO3 must be 1500
mg.  So, in 1800 mg, there is "room" for the 1500 mg CaCO3 and, therefore,
for the 600 mg Ca.  In other words, I think the label really means that you
get 600 mg Ca, not just 40% of that.  The other 300 mg is probably mostly
