I hope you did not get many of the CCI 400 primers.
Federal 205 is generally the primer listed in load data. Fed 205 has a cup thickness of .0225" Then we have CCI 450 & BR4's at .025" cup thickness
Rem 7 1/2 come in at .027 cup thickness. These are the primers I would consider for loading 6mm ARC bolt action upper pressure loads.
The CCI 400 primer cup thickness comes in at .025" look up (primer cup thickness chart) for a reference. The 400 primers will do ok at lower pressures. Though you can expect flattened & cratered primers as you approach upper gas gun pressures much less upper end bolt gun pressure.
