It might be a good idea to bring weapon damage of all weapons closer together
so most weapons become more or less viable. Basically you'd have to rework most weapons to get balanced advantages and drawbacks.
Pistols should have the same damage as rifles. Their big drawback is their range.
I'd give the Mauser a higher range and the 223 pistol a slightly shorter one.
The Magnum should have higher damage (come on, it only has 6 shots).
You could move most better weapons to gunsmith 1 and instead introduce zip guns and pipe rifles with higher damage than the BB gun and the pipe rifle with longer range (around 30?).
They should require very little to be crafted.
Big gun ammo should be harder to craft, but I would make more of them available by crafting.
Rocket launcher should be available without blueprint, but rockets need to be harder to craft.
Energy weapons should be harder to craft and maintain (wear off faster) and unavailable from the start (yes, not even the laser pistol).
Would love to see more melee weapons too and you could encourage people skilling throwing by having rocks lying around on desert maps.
