The OP asked about "pure bee's wax or tallow or some mixture of the two?"
So true. Thanks for setting me straight.
I, also, used to keep bees. Had enough hives to pollinate a small almond orchard each Spring until someone rustled them. I was ready to take a break anyway, but did end up with a small supply of bee's wax from the venture. Great for bullet lube and to waterproof leather (mixed with Neatsfoot or mineral oil). One of these days I'll try making some lube pills, but it always seemed like a lot of valuable wax going downrange.
