How do you handle crafting ammunition in your games?

@michael_demoss Just bought the Gunslinger Archetype from DMsGuild. How do you handle crafting ammunition in your games? Guidelines please
You decide what kind of ammunition you want. Gunpowder? Arcane propulsion? (1/2)

@michael_demoss Decide a base price of mats (10g for 20 bullets?) & Tinkering check (Dex). 10+ makes all 20, lower number make 10 or 5

Most warriors and combat specialists spend their years perfecting the classic arts of swordplay, archery, or polearm tactics. Whether duelist or infantry, martial weapons were seemingly perfected long ago, and the true challenge is to master them.

However, some minds couldn’t stop with the innovation of the crossbow. Experimentation with alchemical components and rare metals have unlocked the secrets of controlled explosive force. The few who survive these trivals of ingenuity may become the first to create, and deftly wield, the first firearms.

This archetype focuses on the ability to design, craft, and utilize powerful, yet dangerous ranged weapons. Through creative innovation and immaculate aim, you become a distant force of death on the battlefield.

Inspired by converting from the Pathfinder class, retooled and altered for 5e and making it more my own, I hope you enjoy.

1.2 changes!

1) Clarified that Grit could not be generated by non-die roll Crits via conditions, like paralysis or unconsciousness. This previously allowed a serious exploit, and didn’t fit with the theme of grit being pulled from a heroic shot.

2) Improved Quickdraw to add your Proficiency to Initiative, as I felt it needed to scale and be competitive with other archetypes/classes based on the flavor.

3) Trick Shot: rolled Leg & Wing shot together, as the seperation was more of an artifact from the ol’ Pathfinder days.
