If we all recycle brass objects from our homes (brass nick-nacks are all over a relative’s house), and turn in our mercury thermometers (for fulminate primers) and tire weights, we could do it.
Mercury is no longer used in primers. They will use the mercury for squiggly light bulbs to break and spew mercury in the nursery. New tire weights are using zinc.
I’ll let you take care of the fulminate of lead (what is currently used in most primers) at your place. Toxic, touchy and dangerous to deal with on an industrial basis.
