Yeah, lanolin and Iso-heet is the way to go. I toss a bunch in a cardboard box, spray them and toss them around until they get fairly well lined. Let them sit about a half hour or so, then resize and tumble the lanolin off in walnut shell with nu-finish and mineral spirits mix (50/50 mix, I squirt in about a half ounce every time I tumble)

Good luck, hope this helps! And remember to trim those .223! That's a big problem with those.
