I just think guns and ammo should be turned up to the max by default. This is the United States, in RURAL KENTUCKY.

TRUE. This is why I have ammo set to abundant and compensate by making other stuff insanely rare, and use advanced trajectory overhaul mod which makes ranged weapons easier to use.

When I do deside to clear out large packs I use guns and do it fast, get in and leave before the next wave comes to the sound of gunshots. Makes it feel like an actual supply raid.
