How To Make Primer Powder H48

H48 is a corrosive primer recipe but extremely inexpensive and simple to make. Essentially - it only has 4 simple ingredients. This is a ready-to-go recipe. In other words - it is impact sensitive so it should be treated with caution. Red roll kid cap powder is a very close cousin to this recipe (also call Armstrong's mixture). If you whack it with a hammer - you can expect it to "go bang" and your ears will be ringing.
