I am not a fan of tumble lubing, I tried and quit using it.
If you can afford it, a sizer/lubricator is the answer.
There are any number of different lubes you can use, in place of the tumble method. A really simple one that is pretty good, is a mixture of about 50/50, bees wax and beef tallow. This is what the buffalo hunters is said to have used.
One way to lube by hand is to set the bullets upright in a shallow, flat bottomed pan. Heat your lube (slowly) until it melts, then pour it in the pan beside the bullets, until it just covers the top lube groove in the bullets. You may need to have your pan of bullets on a very low heat range on a stove,so they are a bit warm. Wait until all is solid.
You need what is called a "Cookie cutter." At one time you could buy them cheaply, but you can make one out of an empty cartridge. If it a bottle neck shell, cut the bottom off and enlarge the neck just enough that it will slide over the bullets in your tray. Give similar treatment to a straighter walled case.
The bulllets will come out without too much extra lube, if your case is right size.
