My wife bought one of these for drying baby bottles, etc. Looked perfect for brass so I bought one for the cave. It is the best thing I've found for drying without heating. I didn't time how quickly it dried but it was definitely way faster than leaving brass on a towel.
Looks like it would easily fit 100 pieces of 308 brass per mat (maybe even 150+, I have it spaced out pretty well). There is plenty of space between the bottom of the mat and the case neck. I imagine you could thread the "grass" into a 223 case and leave the flash hole unplugged...I'm sure it'd be useful for lots of calibers... Anyway, worked well for me and thought it was worth sharing. Hope it helps...
