Making A Leadbelcher

[Yuven]

So, me and some friends of mine are going to play a oneshot of drunken Pathfinder tonight, so the rules are a bit loose.
We are going to start at level 6 and have 2 ability scores start at 18 and roll for the rest.

So I asked the GM if I could play as a Leadbelcher (it was either that or a Bavarian Barbarian xD) and I got the green light for it!

So a few things about my character concept. I am going to carry a huge cannon(Picture for those who dont know what a LeadBelcher is.)
I was thinking that I would Load it with various scrap metal, and have a score of goblins to reload and such for me. I also thought that maybe having a huge beartrap on a chain for trowing might be fun, and ofcourse the beartrap fighting glove as a melee weapon. :D

All of our characters are supposed to be well known mercenaries from our homelands, so we start at level 6 (and end at level 6 since this is a one shot)
So I thought maybe 1 level gunslinger and 5 levels Barbarian might be a suitable way to go.

So what I want advice on is: How would you make this character? Any Feats, Archetypes, or Classes I should think about using?

How would you stat my weapons?

Anything else?

Thank you for taking time to read through all my rambling!

For simpler rules interactions, for the cannon, use the rules for a large Blunderbuss, but that doesn't really approximate the effectiveness of the Leadbelcher's weapon. But you could start from there and tweak it.

I'd go with a race that has powerful build so you can use large firearms. At this point, I'd probably go with the culverin, if possible with an upgrade/ feat that does not knock you prone while you fire it.

You can also go for a musket master and use the good old musket, but in your case something like a culverin makes sense.

Well, Leadbelchers are Ogres, so I'd assumed that his race would be Ogre...

Oh I am absolutely going to play an Ogre

Well, PF Ogres have some racial HD that could be a problem, so you can just use the Half-ogre as a template and say you are an ogre. Your call, though.
