You can just intergrate the lubing into you sizing process with very little added time. Rub your index finger in the die wax tin, grab a case, rub the case with your finger while moving it to the sizing die, and resize. The last thing I would want to do is spray lube over one of my reloading blocks. That may work fine for lubing, but what are you going to do when it comes time to load the cases and put them in a block that has residual lube on/in it?? Lube on a magum rifle or pistol case is very bad ju-ju.
I'm calling B.S. on that comment!
Well, seeing as every reloading manual I've looked through have very clear instructions to REMOVE
ALL lubricant from the case after sizing or loading, would you care to venture a guess as to why EVERYBODY has that instruction in their manual? The reason is that for both rifles and pistols, when the round is fired, a clean case will grip the walls and not allow the case to slide backwards. And as a matter of fact, THAT is why having the correct headspace on a cartridge is important, because if there is an excessive headspace problem with the cartridge, the firing pin strike will drive the case to the front of the chamber, and then the base of the case will stretch backwards because the rest of the case is stuck to the walls of the chamber. This will cause thinning the brass in the base and set you up for the case head blowing off at some point in the future. Now, if the case has lube on it, even if the case has a headspace problem, the case will just slide backwards in the chamber until the case head hits the bolt, and in this situation the resulting pressure on the bolt can be much greater than with a clean case.
If by chance, you still think this reasonably logical explanation of why all reloading manuals have the caution to remove all lubricant from the case after loading is a B.S. rationalization on my part, check this out:
Lyman reloading manual #45, published in 1970, so this knowledge has been out there for over 40 years. If you want to call up the Lyman people and tell them the information in their manual is B.S., be my guest.
