The British Lee–Enfield rifle has a 10 round magazine, and I believe it was reloaded using 5 round stripper clips?
I can see a situation where if you've fired say, for example, 9 rounds and start a reload your guy will use one stripper clip then manually reload 4 more rounds.
It'll take ages to reload, and you'll be stuck in a reload animation unable to do anything about it.
If you've fired 5+ rounds I'd like to be able to use one stripper clip then stop the guy from continuing to manually load single rounds.
