Yeah, putting different rounds in a magazine isn’t that weird. It’s particularly useful if you are using tracers, to notify you when the end of the magazine is coming up for example, and to only have a tracer every few rounds. Even without that, there are reasons someone might have for mixing rounds in a magazine. Obviously, like you said, same caliber is how this is done. If it’s alternating calibers then that’s not great.
