I would also recommend a pellet gun. Accurate for small game, pellets are cheap, and they don't create a ton of noise.
Water is huge. Some way to store it, plus purify it. A couple of ways to purify water should be part of the plan. I have a couple of different filters for hiking, but for extended purposes, something like this: Aqua Pure. It all depends on your environment (urban, rural, etc.), and what you think might be the biggest threats and/or issues you'll run against.
Good post ! Thanks.
One thing to keep in mind is that mice, rats, squirrels and other animals can chew through a plastic bucket with ease.
And they are very good at sniffing out buckets that contain food.
Even when the food is treated with oxygen absorbers and heat sealed in Mylar bags.
Check out post 14 as an example of the damage varmits can do.
We store plastic food buckets in the house and check on them fairly often. It’s advisable to protect food products stored in a barn, garage or shed by storing them in clean metal garbage cans or metal cabinets.
I’ll Google it but not familiar with Gamma lids. Thank you.
