In a safe place (that is anywhere "Momma" won't explode over you doing a project) take a large jar lid, set the bullets upright and use a blow dryer to melt a half stick of bullet lube (Lyman alox or I like SPG Black powder lube) among the bullets, make sure the lube groove is covered. let air cool, the refrigerate over night, The bullets should break out of the lube and be ready to go.

It would be even better if you could match the original lube!
