And your assumption is that Sarel's telekinesis spell is weak? Indeed, it is not.

I don't think he assumed it was weak. Rather, he assumed that even the strongest telekinesis could lift over a hundred pounds. I know a vampire lord can do that, though they have the power of blood magic backing them up. Ultimately, if one can do that, it wouldn't be a walk in the park. The mage would have to exert considerable effort to lift that kind of weight and sustain it.

I'm referring mostly to word choice here, though guns in ES are never something I've really approved of. The developers have never been keen on including them, and I would say it breaks the theme.
