A complete teardown and cleaning of every individual part may well be in order. The fouling problem NSB referred to is getting enough wax in the chamber so the rounds are cushioned and slowed by it as they chamber. This results in all the excess headspace being forward of the rim. When you try to fire it, some of the energy from the firing pin blow is absorbed by seating the round the rest of the way into the chamber through that high viscosity lube, and that can be enough to cause a failure to fire.

Solvent-soak and dry and treat the springs and firing pin and anything they touch for 72 hours in Sprinco's Plate+ Silver and wipe off all the excess. This makes them slip against each other better to maximize firing pin energy.
