Save some $$$$, and get the Alox "White Label" version......
You can buy a QUART sized container of the Alox stuff (White Label) for the same price as a mere 4 oz container from Lee.

They call the generic version XLox, so there's no lawsuits. It's the exact same product.
In fact, it's an even better deal than the Lee version. Lee uses a solvent to "water" theirs down a bit. The stuff from lsstuff is very very very thick. If you thin it down to Lee's version, you'll end up with at least 1/2 gallon of the stuff.
I use an old cream cheese plastic container (margarine container, or what have you), and put some of the lube product in. I add some mineral spirits, and stir with a stick until dissolved. Then drop a few hundred bullets in, put the lid on, hold onto the lid tightly, and tumble the container in your hands. The bullets will get coated all over with the lube.
Take them out of the container, leaving any extra lube in the container (waste not), and place the bullets, butt end down, on a sheet of wax paper to dry over night. When in a hurry, you can put a fan on them, and they will be ready to pop into cases in a couple of hours. Make sure they are dry to the touch all over before loading though.
The big cast bullet grooves are for lubing the other way. The micro-grooves are called "tumble lube grooves", and I have just described that technique, and where to get the product.
Oh, and for the other type of lube (the kind you use in a lubricizer), llstuff also has that, really inexpensive!
And, speaking of lubricizers... that's one additional tool that you might want to look into. They're not all that cheap, but they do the sizing of your bullets for you. Especially important, depending on the gun you are running, the quality of your castings, and how fussy you want to be. Most reloading books tell you that you can load the cast bullets as-is, but I found that I can make them (the bullets) more precise by sizing them. Lubricizers come as a bench mounted press, and you pop in different tools to do the sizing. I bought the Lyman version (Lyman 4500), and their inserts come in increments of .001", and they have the top "punch" in varying bullet nose shapes. That is to say you would use one punch for SWC, a different shape for RN, FN, etc.
So, if you want .355 bullets, you buy that insert. If you want .356 bullets, you can buy that insert, etc..... The molds aren't necessarily all that accurate, and get worse if you have any "parting line flash". The sizer fixes the bad issues, and assure that the bullets are exact in diameter. If you properly fill the cavities, you won't affect the ability of the micro-grooves to accept the tumble lube.

I run my Lyman 4500 without the heat rod installed, and without any stick lube in it. I am only resizing in it.
