any chance you could split "cartridge" into two different mods: "Caliber" and "Magazine"? you wont need to change textures by doing this, and it'll allow for one additional awesome customization.

- Mag size adjusts burst count, mass, and bigger mags lower accuracy. ex. short mag, normal mag, long mag. less burst/more accy > standard/no change > more burst/ significantly less accy

- Caliber adjusts dmg and range accuracy. ex.
> "hollow point" (9mm/pistol)- more dmg, less pen, higher short accy
> "standard" (5.56/slug) no changes, default
> "FMJ" or "AP" (7.62/50Cal) increased armor penn, lower short range accy, higher long range accy
> "Sub-Sonic" adds hunting stealth%, lower base damage and armor penn, longest range loses accy.

this way, there's even MORE customization, mag changes dont have to be such a trade off, since you can have "weaker" rounds to keep stats balanced. and if you take the AP rounds with higher burst count, you significantly get punished on accuracy as a fair trade for the damage.

you can have a gun for each colonist specialty/role, a wall of lead, or just about anything.
