Will I die using this tube?

I want to build (legaly) an rpg 2. I have a fire control group and this tube I’m pretty sure will be safe for a black powder charge but I just want to make sure and ask the experts here. It’s a 38.2Mm which is close enough if I’m making my own ammo anyways.

Thoughts? Warnings?
