Motor Mica

[1shot]

Has anyone ever used Motor Mica as a inside neck lube for seating bullets? I was rummaging through my shop and happened upon a can of it. It is very fine and slick. I don't know why I have it, but thought I might put it to use. Anyone have any experience with it?
Thanks,
Lloyd

Has anyone ever used Motor Mica as a inside neck lube for seating bullets?

Not for seating bullets but I used it in the neck of the case when pulling the sizer ball through the neck when sizing. It worked on cases that did not require lube but it did nothing for cases that were work hardened. When seating bullets the alignment between the neck and bullet is the way to go when seating bullets smoothly.

Then there is bullet hold, I want all the bullet hold I can get.

Haven't seen that stuff in many years! Not that I have looked for it. I used it back in the 70's for neck sizing.

That is the lube supplied with Forster Case Neck Graphiter.

I have the small snuff looking can with the small hole in it for lubing necks. I do not use it but have it just in case. I also have the RCBS case prep center that is designed for lubing necks; I get better results with a wire bore brush turning in one of the 5 rotating positions than any lube I have used.

Well i have a 1/2 lb. can of the stuff so I loaded some ammo today to see if there is any difference in seating pressure. I have an arbor press with the PSI gauge on it. It appears to lower the seating resistance somewhat like graphite does, but not a big of a mess. I'll see how they shoot in between the rain drops!

White Mica was the first neck seating lube I ever used. I now use the Imperial dry lube in the ceramic ball jar but only because it is less messy than my original method using mica but mica worked fine for me back then.

heard it used as a bullet coater, like moly

If you wrap 0000 steel wool around a bronze brush and then spin it in the case neck you will never need any lube to seat bullets at all. Will seat smooth as silk.

I use it in high performance shot loads in 10 and 12 gauge. I tried some in with ceramic beads from Redding after the graphite was used. I went back to graphite as I didn't think it worked as well, JMHO.

Now that I think about it, the can that I have was in my shotgun reloading section of my shop. That is probably why I bought it in the first place. Thanks for jogging my memory.

Forster makes a neck lube kit that uses motor mica.

I have some .308 Win loaded up that i used mica to seat with. Haven't tested it yet but curious to see the difference if any. Didn't really feel a difference when seating but i may not have used enough honestly. dipped the neck then blew on it which probably removed most of it. I will also be testing a batch using a bit more as well. I am a bit unsure of how cases with less measurable neck tension (more neck ID before seating) differ from case necks with less ID before seating but used with a lubricant like mica or graphite to reduce friction measure up. I have never seen a scientific, deterministic study on how both affect "bullet hold" and release upon firing, and how the differ, etc. I could make assumptions but i try as hard as possible to not. Either way i will go by what i see on paper. Should be interesting. Jesse
