I was at the Gun Runners making some ammo and before I started I was at 260/290 and when I left I was at 384/290. I don't know where it came from, but any ideas on how to get rid of it?
P.S. I'm playing normal mode.

Are you carrying the lead from when you break ammo down?

Try putting that in a container, see if that weight suddenly disappears.

That was it, thank you very much

No prob, just wasn't sure if that would've been it because I've only ever played it on hardcoe and that's what caught me out, too. Was a total "derp" moment for me, went from carrying 200 lbs. of it to suddenly seeing my carriage weight drop to about 30 lbs.

Kind of weird that the ammo has no weight in normal mode, but the lead from it does.
