Hi . I occasionally use a small computer vac to clean up powder dropping from my Progressive press. Would there be any issue if I reused this powder? I ask this because my bench is in an area that may be prone to have dust and/or minor sawdust particles. Of course I would try and sift out as much extra debris as possible, BUT would a minor flecks of dust cause any issue? FYI this is just really a curiosity question as since I'm a newbie to reloading, I have no immediate need or plan to reuse the powder unless necessary in the future. My priority is to be safe before frugal (stupid).
