I TL or Ranch Dip all my bullets and on rare occasions I will pan lube some bullets for a specific use. Here is a test study done using Lee Alox with various firearms and bullet types.
Extensive Test of Lee Liquid Alox
Needless to say I TL both TL design and Non-TL bullets,some are plain base and some will take a gas check,I don't always use the gas check though it mainly depends on alloy,BHN velocity and pressure I'm shooting the load at. I've run tumble lubed bullet form 800 to 2K fps. with and without gas checks with no leading issues and good accuracy. Standard 357 Tl bullet load runs around 1200 fps.
The only issues I have with the methods used in the test above is that I TL before sizing and TL afterwards,I also don't thin my Alox quiet as much I use 1/2 oz. of MS per 4 oz. bottle of Alox or Xlox which is the same lube and what I use now it cost around 50% less. I also warm my bullets and lube bottle on a heating pad prior to lubing it give them a much more even coats,warm bullets just coat much better.
