yes, lube does collect int he die.
I know some lubes are not compatible, and you must clean the old lube out.
for instance.. the hornady 1shot spray lube says that if you hav ebeen using a water based lube.. like the rcbs roll-pad lube.. that you need to clean the dies before using the ?wax? based spray lube. etc..
