A small, more for fun idea than anything, but Blaze Rods would be able to be used by Railguns as ammo. Perhaps they could have the power of Iron Rods, but have a high chance of burning the target as well.

A railgun operates using electromagnetism, so the projectile needs to be magnetic. I’m not sure if Blazes are metallic or not...

sulfur contamination (assuming sulfur being main part of blaze rods) distorts magnetic properties of metal, though it is only described as impact on permamagnetic properties and i could not find any source on the effect regarding electromagnetism i would say technically @TeamSpen210 is right

but having blaze rods as fiery infused projectiles would be nice, though i would make it's break chance 100% as they are fragile by nature (can be crafted by hand into dust)

Friendly reminder that IE's railgun is technically a linear induction catapult, which uses a sled on which the projectile rests. The projectile itself doesn't need to be magnetic. (see the manual entry for the Railgun)

And yes, I'll consider blaze rods when I finally get around to reworking the railgun.

Oh right, this is implemented now.
