@13org In the original RP I had a second character who did use what could be considered a very advanced flintlock gun, but that character was based on his genius while being physically unable to do anything but hate physical education. Given that we are a few decades into the future now I'd concur with @TheDoctor's estimate.
My character's suffering from chronic hypoxia, otherwise he wouldn't deliberately or at least on a willing-to-take-the-risk-basis contribute to the bloody mess unfolding on Seren's Folley's doorstep while he's one of the very few hunters who could do otherwise given his equipment.
Air's just too thin when one's head is so high up in the air.
