The primary purchasers of the product are water treatment plants. Pool owners are just discovering it, but most aren’t seeing the advantage of having a non-degrading bleach supply.

Personal defense items – such as rifles and heavy firearms – are going to be increasinly hard to manage the farther you move from steady supplies.

If you want to stay highly mobile, switch down to a .22LR polymer rifle such as the Savage survival rifle or similar. Lightweight, collapsible, and perfect for hunting game. Loaded with subsonic rounds, it can also be a lot more efficient than heading off a target with a loud 30-06.
