WD40 is a penetrating oil, light weight lubricant, etc. that also displaces water. If one were to look it was actually developed as a lubricant to be used in orbiting vehicles and machines for the space program.WD40 is NOT a lubricant. Its a water displacer
I have never seen that particular offering from them, and I just did a restock on my shop supplies so should have if the stores in my local had it. I see is has Teflon in it. Is there another dry lube in it as well? I've just been using the lanolin I use when I swage my slugs, it works just fine but holy cow does it like dust and dirt.I use a tumbler to clean my CPHP with some Dawn, rinsed and tumble again. Lay them out on a towel flat to dry, weigh out about 117g worth of pellets then put them in the top part of the tin, use a toothpick to lay each pellet on its side, then a light spray of WD40 Drylube.
