Quick Question,in the Wiki it says that there are 3 types of ammo that get boosted by the Pyromaniac Perk,I will put in here just like the Wiki.

Affected ammunition
.50 MG, incendiary (burn damage only)
40mm grenade, incendiary
12 gauge, dragons breath

So on i'm not sure if all the ammunitions listed above will have a bonus just to fire damage or if only the .50 MG will have fire damage boosted and the rest will have everything boosted,please answer.
