[QUOTE="Greenhornet_au, post: 659961, member: 8767"] Checking if it is soft lead would mean that you have to damage it slightly, because you would have to try to press a knife blade down into it. If it is 'pure lead' as the projectiles were, a knife blade sharp edge would press a groove or even shave a bit off the side. But this would be a last measure to test. An XRF Xray scanner would be nice to use, some precious metals dealers have them, but may charge a fee. I guess a specific gravity (SG) test would be easiest, this is the best link I can find and it has a video explanation. SG = Density Specific Gravity of LEAD = 11.34 Follow this to do an SG test - use a cotton thread tied around the item when hanging it in the water.
