Ah, I see. Ballistic gun development is at that period somewhere during the American Civil War and likwise, 1860s to early 1870s.

Yes. With the advent of manalock weaponry, ballistic weapons have begun to slow down in the race. That said, ballistic weapons are still commonly utilized in both the civilian and military markets. For civilians, they're cheaper and easier to maintain. For militaries, ballistics are more capable of piercing armor, especially since most modern protection in Yggdrasil revolves around diffusing mana attacks, and less about stopping physical projectiles.
