Guns and magical bullets

[Derek Dalton]

Apologize if this is in the wrong section. Keep hearing about an ability and or feat that allows a person to reload a firearm with magical bullets of Force. Since I plan on playing a Gunslinger soon I am trying to find it. Any and all help is appreciated.

I think you're talking about Spell Cartridges?

There is a feat that lets you do force damage.... small amount, but still

Spell Cartridges (Combat)
Source Heroes of Golarion pg. 4
You can fire bullets of arcane energy when your ammunition runs low.

Prerequisites: Arcane Strike, ability to cast arcane spells, proficient with firearms.

Benefit: While your gun is imbued with power from the Arcane Strike feat, you can fire force bullets instead of regular ammunition. A force bullet deals 1d4 points of force damage for every five caster levels you have. Force bullets do not use black powder or ammunition and count as magic for the purpose of bypassing damage reduction.

sites to look up stuff:
Archives of Nethys official PF1, doesn't have everything (mostly missing rules & extra clarifying/discriptive text).

d20pfsrd better search but essentially a conglomeration of posted rules with some unmarked edits. Normally search this first then try AoN for official text (sometimes that data isn't on the website, thus break out your book or purchased pdf).

PF1 Class Guides. Your GM probably won't agree to some of the crazy tricks so it's about 90% practical and a guide. Many have fallen behind the publication stream.

There's the Advice forum, General Discussion forum, and the (눈__눈) Rules forum here on Paizo messageboards. 8^)
