What lube for case mouths?

[Moman]

What lube are you guys using inside the case mouth when resizing? I usually use the Mica dry lube but the cases squeel a bit. I have always heard that case lube can contaminate the powder charge.

I use Mica too. Don't much care if the necks squeal a little, just don't want to hear of a lot of it.

A very light smear of Imperial. No problem with contamination.

I use powdered graphite when I'm using 'standard' dies,a small amount on a case neck brush is ample,just make sure you tap off any excess.This won't contaminate powder or primers.
I also polish my expanders down to .002" smaller than bullet diameter.This amount of neck tension has worked for my 'standard' hunting rifles.
My long range/target rifles use very different processes to this,neck bushing dies etc.
