I packed my hanloaded ammo inside a TSA locked Pelican 1200
70 rounds of 30-06 handloads total
50 in a Berry's clear plastic snap box.....foam in the lid
20 in a slip top Berry's clear plastic box.....foam in the lid
I put a Sierra reload data sticker on each box filled out with all the load data
All locked up with a bunch of room to spare I put my pocket knife and some other small stuff inside
Dropped it all deep inside my TSA locked duffle
