A chamfer doesn't necessarily fully correct a primer crimp. You're putting in a slight bevel which should ease in a primer, but if the base of the primer hole was deformed by a heavy crimp, you may be out of spec enough to choke in the primer pocket at the bottom.
I also used an RCBS Primer Pocket Swager Combo tool 9495 on them. That should have reformed the pockets.

Some of the primer holes seemed to have very little bevel, but none had any apparent crimp.
