as Ive mentioned several times through the thread..... Are there any known potential down sides or problems with using colored nail polish or lacquer paint on primers? (around the circumference, like .mil loads sometimes are) My primary reason is for identification of the loads. Ive usually used different headstamps for varying loads, but Ive come into a bunch of similar brass I want to use for several different loads and a couple bullet weights of otherwise identical factory loads (or nearly identical). First thought of using colored nail polish (which I already have), can it be thinned a little to make it easier to use without causing problems with primers? Im doubting it would be a problem, but I certainly don't know everything, so am asking. Just labeling boxes is great for range use. I tend to end up with piles of speedloaders and speed strips, ziplock bags, deerskin bags, cloth bags, ashtrays, consoles and cubby holes in vehicles, pockets, and who knows what all else with cartridges in them. Labels dont do much good once the shells are out of the box, if they ever even go in a box.
