Never had any problems with the cast bullets
I've Lee aloxed.
Always did it just like the Modern Reloading
book said

I use a plastic bowl and do 10-12 at a time with
just a small bit of the alox. Swirl em around
slowly until they're all coated and let em dry
completely on a sheet of wax paper.
Mostly done the R.E.A.L. muzzleloader bullets,
but a good many for 38/357- 44mag SWC cast
too. Nary a problem ( so far)
Might be too slow of a process for some
