Shooting a jezail rifle

[Battara]

I'm of 2 opposing opinions:

1. I am fascinated by scientific exploration of the shooting of these weapons

2. I am highly cautious because of the aging of metals. I will never shoot off my Moro lantaka cannon because it might be anywhere from 150 - 400 years old and blow up in my face. (not unknown for some owners of old lantakas who shot off their cannons).
