A round has a brass case, and lead bullet, if you only touch brass you cannot get a result for lead, unless you handle lead - prove that nobody could handle/load rounds into gun without there being any traces of lead on the hands/fingers?
Who's to say the ammo used in the shootings was not eley sub-sonic? but high-velocity rounds were the bullet is copper plated. Since my last laptop died, I will have to re-build my research over again!

There is a log, stating high-speed loads were used in one magazine 10shots? and eleys, and the EP came back to the scene to remove the eley subs to false evidence against Jeremy?
