I watched a couple of videos of guys making homemade bullet lube. What the purpose of adding a cap full of STP oil treatment to the mix? Thank you
 
They thought it would make the lube extra slick and protect the bore.

From here on, the comments are speculative. The purpose is to add an unnecessary step and have a mystery ingredient that makes their lubricant unique. More likely it will combine with the powder fouling to make a hard crust that justifies extra cleaning. The extra cleaning may be a gain in performance accuracy.

No better than one part bee's wax and 6 to 8 parts of a high temperature kitchen oil (grape seed, avocado for the exotic, olive or canola oil). This not speculation, all of these lube mixes will perform. Some do better (not melt) in heat and others stay softer for use in cold conditions.
 
I really like beeswax and a little olive oil. The fouling stays soft and it's a nice consistency in all temps. But, this has nothing to do with the OP's question....
 
It's been my observation and experience that the more complicated and involved a lube recipe is, the less actual benefit is derived.

I remember a lube that I mixed where the recipe called for STP. As usual, the inventor of the recipe rarely has any qualified explanation for the ingredients!:rolleyes: I think the one I'm referring to was a BPCR lube.

Last thing I want to do is discourage the fun to be had experimenting with lube. I finally ended up with animal fat and the simplest way to acquire it for this suburban boy is a package of Morrell lard at the supermarket. :)
 
There is a modern DIY gun lubricant/solvent for modern guns that some folks like. STP, Kroil, and ATF in equal parts. I have tried it on modern guns and it works fine, and is less expensive enough for folks doing a lot of shooting of several guns to warrant the use of something of that sort. It also has the advantage when out in sparsely populated areas, that you can usually find the ingredients at a car parts store, or a well stocked gas station, when the local gunshop is closed and/or a long drive away. For most folks, I'd say use a commercial OTC solvent followed by a lube/rust preventative, if not a commercial all-in-one product.

For US..., as the members have mentioned, some sort of animal or vegetable fat, and some beeswax to thicken it up, works great for a bullet lube and keeping lock parts going. The amount of beeswax is based on how "thick and hard" (that sounds naughty) you want the end product to be. Lubing bullets for BP cartridge guns at least a 50/50 mix of beeswax and the fat. Probably more like 60/40. Summer and fall round ball patch lube..., I like 1 part beeswax; 2 parts olive oil. Lard works too. Very cold winter, maybe 2 parts beeswax, 8 parts fat, or even no beeswax.

Don't use paraffin in place of the beeswax, as the melting point is too low.

You would have to ask them. Everyone who makes up a lube has a reason . . . or not . . . for adding things or forming the basics for the lube.
