Wet tumbling and the weight of brass

so-shiny-im-gonna-dieAfter wet-tumbling my first batch of brass the first thing that came to my mind was that scene from Despicable Me: It’s so fluffy shiny I’m gonna die!

So I went ahead and did my already dry-tumbled “clean” brass over again, leaving my with piles of oh so shiny brass. But… how much? Well, counting brass kinda sucks when you’re talking thousands per caliber, so better put it on a scale and do the math.

Here’s a handy breakdown for future reference:

Case grains per case grams per case cases per lb cases per kg lb per 1000 kg per 1000
