Shooting bag fill?

[offthebeatenpath]

My better half is a seamstress on the side and has a room full of machines, plus bolts of waxed canvas and leather from her bag making business (shameless plug for RaenWorks Bags).
I’m going to have her make me up a couple schmedium knockoffs for personal use.

What have you guys found or used for bag fill? I know there’s a lot out there, I don’t need ideas, I want to know what you’ve used.
I see that Box to Bench Precision sells the Spex-Lite branded stuff, and they’re pretty proud of it.

What else have you guys come up with?

I can’t tell if you’re here for the suggestions or if you’re suggesting using popcorn seeds
