On a related note, I usually left the spare mag alone

I'd just top off the one under the bolt as needed.

This is just one of the many advantages of detachables: IMO, it's much easier to do this than it is with most blind-magazine rifles.

Of course, a lot depends on the design of the box itself, plus the means of releasing it. On some rifles, they're both simply hopeless, but of course those examples hardly count.
