I am under the impression this is OGL (as it has nothing to do with Golarion or lore in general). If it is not, let me know and I can delete it/have a mod delete it.
Automatic Weapon Quality: A weapon with the automatic weapon quality fires a burst of bullets with a single pull of the trigger, attacking all creatures in a line. This line starts from any corner of your space and extends to the limit of the weapon's range or until it strikes a barrier it cannot penetrate. When an automatic weapon attacks all creatures in a line, it makes a separate attack roll against each creature in the line. Each creature in the line can only be attacked with one bullet from each burst. Each attack roll takes a -2 penalty to account for recoil, and its attack damage cannot be modified by precision damage or damage-increasing feats such as Vital Strike. Effects that grant concealment, such as fog or smoke, or the blur, invisibility, or mirror image spells, do not foil an automatic weapon's line attack. If any of the attack rolls threaten a critical hit, confirm the critical for that attack roll alone. An automatic weapon misfires only if all of the attack rolls made misfire. A single attack with an automatic weapon fires 10 bullets. An automatic weapon cannot fire single bullets that target one creature. When taking a full-attack action with an automatic weapon, you can fire as many bursts in a round as you have attacks.
Come on! What about weapons that you have clips of 50 for?
