Do any of you have any suggestions on what I should do, or how to identify them so I can find a recipe in my manuals that is safe?
I'm guessing that you're referring to reloading these bullets. If that's correct, just use your powder scale to weigh the bullets, and measure the OD with an accurate tool...... micrometers, or accurate calipers. If the weight and diameter is what you want, the scrape the coating and find out if the bullets are plated, or actually jacketed. At that point, you'll have the bullet weight, diameter, and composition. The manufacturer doesn't matter all that much once you know the bullet specs.
I have no experience loading tracers, so I'll have to defer to those who have......
If I missed something, give me a bit more info and I'll try it again.
