On Number 2. Calibers to consider due to their prevalence:
1. .22lr - Doesn't pack too much punch but it's good for hunting small game. It's very easy to stock >10,000 rounds of this ammunition.
2. 9mm - Most common handgun caliber in the world and has a high enough muzzle energy to be useful over longer distances with a rifle or carbine length barrel.
3. .308 - Most common hunting cartridge and packs a huge punch. It's effective range is 800m and can drop a moose.
4. 12 Gauge Shells - Any engagement under 100m is where 00 buckshot shines. Shotguns are absolutely gruesome close up and much more effective than many other options. Super cheap as well.
5. 5.56 / .223 - This is the cartridge used by most AR15 pattern rifles in the hands of both the military and law enforcement.
Note: Buying ammo is super difficult/expensive right now since the start of covid and the protests in June. It'd be best to stick to .22lr and 12 gauge if you don't already have a supply..
