For shooting cans or targets lube as much as you want, and expect malfunctions if you lube too much and the lube gets fouled. For defensive or offensive use follow the maker's and/or issuing organization's directions, where weapons are expected to be cleaned very well and often kept surprisingly dry. The more sand and dust in the area, the drier the weapon.
In spite of the complaints about the need for a better lube for the M16 due to jams in Iraq, the last tests by the military that I saw found that BreakFree did better than the other recommended 'botique' oils.
