I think it's impossible to gaul carbide w/ a brass case. What I have found is really clean brass requires more force to resize. One reason I am NOT a fan of ss/liquid tumbling for pistol cases, the cases are too clean, squeaky clean, & need a bit of case lube for best results.
Dry tumbling w/ a tsp of NuFinish makes the cases clean, shiney & a little slick. You always want to clean cases BEFORE sizing to keep grit out of the die. It can embed & then scratch the cases. Not so much in carbide, but certainly steel rifle dies.
Carbide pistol dies do NOT need ase lube. Sure, things run smoother with it, but it is NOT needed. The few carbide rifle die sets available still MUST BE used with case lube or the cases will stick.
