It seems like the dev won't patch the gun to take .357, so here's your obligatory late guide.

TL;DR - Go into the mod's scripts folder, open "PFO357MagnumRevolver.txt", and replace AmmoBox and AmmoType with a .357 ammo type of your choice for both variants of the weapon. To revert changes, just unsubscribe and resubscribe to the mod.

----------------------------------------------------------------------------------

Step 1 - Have a mod that adds .357 as an ammo type. Shouldn't matter which one, but do note that my steps may very from what you have to do.

Step 2 - Open up your file explorer and find the mod that adds in .357. I'll be using "Gunrunners Weapon Pack - VFE Expansion" for this guide, so I find folder "2873405334".

Step 3 - Navigate to the mod's scripts folder and find a .txt file that (probably) either says items or weapons. Open it up with your notepad of choice, hit ctrl + f, and search for 357, .357 or anything you think will help you locate it. Keep this tab open or copy the "AmmoBox" and "AmmoType" to your clipboard.
- Pers. Note - With GWP, I opened up "GWP_Weapons.txt" and searched "python" and scrolled down to ammo data. I copied "GWP.357Bullets & "GWP.357Box"

Step 4 - Go to this mod's folder, open up scripts, and the open "PFO357MagnumRevolver.txt".

Step 5 - Locate "AmmoBox" and "AmmoType" again and replace the ammo with what you copied. Make sure to save changes once you're done!
- Pers. Note - In this mod's scripts, AmmoBox and AmmoType are a little away from each other.
Just scroll down and you'll see AmmoType. Using GWP, my ammo looked like "AmmoBox = GWP.357Box," and "AmmoType = GWP.357Bullets,"

Step 6 - Make sure you save changes and open your game. If they didn't apply, try changing "PFO357MagnumRevolver.txt" to be read only and/or make sure you edited both revolver variants. If it still doesn't work then err... Sorry for the time waste bro. Try again?
