Not really... for a few reasons...

1. You'd have to be really negligent in lube location on a gun to get the case head area wet enough with lube to seep into primer pockets, and

2. The booger eaters over on ARFcom posted some window licking methods to render primers inert. Most attempts at soaking them in oils and stuff failed to kill the primer.

All things equal, sealed ammo is a plus. But not worth going to a lot of trouble to get.
