Straight walled pistol cases sized in carbide dies do not need lube and is a waste of time and resources. Compound structure steel dies for bottleneck rifle (yes, 223 as well) will require lube along the case body as if rolled on a stamp pad. No lube required on the exterior of the neck. Pistol cases can last 40 loadings without ever being lubed.
Most rifle rounds require the inside of the neck to be lubed for bullet seating. If I use dry tumbled once fired 223 cases I don't lube the inside neck as the chalking carbon film left behind from the tumbling is lube enough. But that's just me.
