I'm slowly moving to lubricating all my handgun cases before sizing. It just makes sizing easier and since I tumble after sizing anyway, the lubricant gets cleaned anyway.
I've started with lubricating 44 Magnum/Special, 45 Colt, and 460 Magnum but am starting to lubricate 38/9mm caliber cartridges, 40 S&W and 45 ACP as well.
I use a spray lubricant and it does not take very much.
