Changes
Firearm calibers are subdivided into three informal categories: <span style="color:#0000AA">'''(P)'''</span>istol calibers, <span style="color:#AA0000">'''(R)'''</span>ifle calibers and <span style="color:#00AA00">'''(S)'''</span>hotgun calibers.
Calibers listed below may also be sorted by base [[Pain]] damage (to give a rough idea of power), metric/imperial notation, [[Recoil]] value, and amount of compatible base [[weapons]] (including [[weapon accessory|accessories]]). The amount of base Pain provided for shotgun calibers is that of '''FMJ slugF-Slug''' projectiles. For more information on shotgun projectiles, (see [[Ammunition#Shotgun caliber projectiles|this section]].for more details)
The amount of compatible base weapons is only meant to be used to get an idea of how common ammunition of this caliber is. It does not take in account cross-caliber compatibility (e.g. .38 Special can be loaded and fired in .357 Magnum revolvers) or rare calibers (see below).
