I want to keep bullet samples from my guns to help with identification in case of theft. I figure that shooting into modelling clay (or...? Water would be ideal but is messy) with very light loads should do the trick. Calibres include .222, .303, 45-70, 9.3x57, 44 Mag. & .45 ACP. I want to use really minimum loads, basically just enough to get the bullet safely out of the barrel. Powder-wise, I have W231, 2400, RL 7, RL15, IMR 4895 & H335. How light can I go and what are the risks?
