I cleaned all the bores with a copper/nylon brush and solvent, and even used a .40 caliber brush. Still had the tightness but noticed some longitudinal and circumferential scratches on the empty casing, so I used spray adhesive to attach some 1500 grit silicon carbide paper, that I use for honing chisel blades, to a 0.367" diameter pin and carefully polished the bore. That fixed the problem.
Maybe one of the casings had a rough edge and when it expanded it scratched the bore when I extracted it and then continued to hinder extraction.
Thanks for all the suggestions; without them I'd probably have paid somebody big bucks to do the same thing.
