I've noticed a few people don't know how to load their gun (I think). Anyways, these are just a few things worth noting if you have a firearm in Olden.
1. How to load the thing: It's not as hard as you think. Gunpowder down the barrel, then in the hole beside the hammer and then load the bullet. If it's a matchlock, be sure to pull the hammer back FIRST... for obvious reasons.
2. You can't really load it and put it somewhere if you need it later. The gunpowder can go out the barrel, out the hole beside the hammer and the bullet can even roll out. You might be able to get a custom design to prevent this but if you didn't ask for it you don't have it.
3. Don't load too much gunpowder. I haven't seen this happen but just in case.
And that's kind of... it.
