This isn't a bad idea.I've taken to salting a few rounds in random pockets of my gear. Found 4 .444 rounds in my bino pouch the other day. Of course with my luck I'd have carried a 7x57mm if I actually needed the rounds in my bino pouch...
I've thought of sewing a few loops for rounds onto my saddle so I can have a few spare kicking around, maybe I'll do it.
