Excellent, thanks.

So, for the M249 SAW, it looks like we have a range increment of 300’, damage 5d10, full-round action to fire, and a full-round action to set up before firing.

From what I can gather, it looks like 600 rounds is the limit before it needs to be reloaded. Firing 100 rounds per minute means 6 minutes of constant firing before a reload, which should cover most encounters. But if it does need a reload, how long should that take?

Also, can the weapon sustain several minutes of constant firing without jamming? Maybe a 5% cumulative chance of a jam for each minute of firing?
