Get ya some old film canisters, they will fit a synthetic shell belt and are waterproof.

Gunner, I've tried several ideas in place of the vials
I went last year to walmart to the camping section...
bought those "waterproof matches" in the little orange cylinder- it has an o-ring
I just tossed the matches in the trash and used those tubes, they were bright orange to boot
they are meh....'ok' for hunting
but I'm looking for a big set for some extensive range testing. It's a bitch toting your scale to the range.
