Does anyone know what type of lacquer is used for the rosette crimped blanks? Where would I get some from?
Thanks |

Generally, ordnance lacquers are basic "nitrocelulose" lacquers. In other words, nail polish, but thinned way down. You can use nail polish and lacquer thinner, or get model airplane "dope," which is purer nitro lacquer than nail polish and comes in less "extreme" colors.

Most are butyl dope. Get some acetone and use it to dissolve some old single based powder. Use an old jar to do this. It takes a while to dissolve. Some black ball point pen ink will dye it to the purple shade you want. It is an aniline dye so it will burn It is a dark purple with no pigment unlike India Ink which is just fine carbon black. Where to get ball point pen ink? From a failed disposable ball point pen. Wear gloves, it can be messy. |

Most are butyl dope. I've made blank laquer with Varget and know it works. Just be careful dissolving it because it is like tapicoa when acetone is added. Takes a while to dissolve as it forms sticky clumps. For ~20 grains of Varget, it takes about an ounce of acetone. Sprinkle the powder into the acetone, then stir for a few minutes and let sit for an hour. Put a tiny drop of ink in it and stir well, thinning as needed. Without dye, it is yellow-green once the graphite settles out. Also great for sealing primers and shotgun crimps. |

Now I have a use for the small amount of powder left-over in a can, other than sprinkling on the lawn.
Thanks Keith. |

Wow, good info. Thank you. Can this be made and then stored for later use? Sealed in jar or something?
Is there something commercially available? |

Ok so I just watched a couple of vids on youtube about how to make nitro lacquer with acetone and ping pong balls. Any thoughts?

Flamethrower this is what I use for sealing my primers, Valspar spray laquer. Black colored high-gloss. I use a small philips screw driver to apply. I spray a small amount on the white plastic cap and dip the screw driver. The cross on the screwdriver holds enough of the laquer to coat around the primer. I have not tried it on rosette crimped blanks do so experimentation would be at hand.

They are somewhat less flammable than NC. And quite expensive compared to waste single base propellent. If you have a good container, it will stay good for a long time. If it dries out, just add more acetone and wait. NC is like starch in gravy, it doesn't take much to thicken the acetone. |
