I got mine from e-bay, tho I cant remember which company.
He sells the 50/50 lube or other mixes and 2lb cakes of alox.
I just mix it 50/50 with beeswax I got from a beekeeper and add 10% parafin wax to mine.
I really like that mixture. I use it in everything from 380 and 45 auto to higher rifle loads.
I've went to 2800fps with no leading that I've found so far.
