Any bullets can be lubed with tumble lube. I have the 200 grain semi wadcutter mold for .45 acp with the standard lube grooves. I tumble lube them, and shoot as cast when the lube dries. I wait about 2 to 3 days for lube to be completely dry. No problem with lead in any of the guns I have shot them out of. They even fed well in my friend's PT1911, and a HI Point carbine.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
