I will again repeat my warning about using matches, toy caps etc as primers..
They all contain potassium chlorate, the residues from which is what eats your barrels if you do not clean them quickly and with a water based detergent cleaner!
Can I also point out that crushing or milling many of the products involved is never carried out manually in industry, for some very good reasons! Primer plants, even commercial ones, blow up at regular intervals and are designed with this "feature" in mind..!
...you have been warned!
