I recently read of another cast bullet loader using spray chain wax for lubing his bullets.
Sounded like it would be worth a try so I bought a can at my local motorcycle parts store.
The brand they carry is Maxima which is a non-petroleum based lube.

I sprayed it on some bullets and it looks and they feel pretty much like Alox coated bullets.
I also sprayed some bullets prior to sizing and they pushed as smoothly through the die as any other lube I have used and I tried some on paper patched bullets prior to resizing and that seemed to work well too.
Now, to get out and shoot some.
Any thoughts on this technique?
