For rifle cases I would use just about anything else other than One Shot.
Arguably the "best" is Imperial sizing wax. A little goes a long way and I've never even had a case suggest it may get stuck when using it. But the only real way to apply it is to rub it on with your fingers so it's fine if you are doing a limited run of cases. And because you use so little it's really up to you if you want to wipe it off the case afterwards.
For volume I use lanolin/alcohol for a bunch of different reasons. It's cheap to make, it smells like cheap vodka and not some toxic chemical concoction, it goes a remarkably long way, it's incredibly easy to apply - you mix it in a spray bottle sop you just spray it on, then you mix the brass up a bit. I use a plastic bin the same size as a 24 beer flat. Just fill it up with cases, give them a few sprays then mix them up, a couple more sprays mix, and you are done. Downside is that you probably want to remove the lube. You can wipe them off with a rag with a bit of alcohol on it or you can throw them in your tumbler with walnut shell and a squirt of mineral spirits for 20-30 minutes to clean off.
