You my girl are a brave shooter! That glass wouldn't last two days around me. Maybe you could suspend an old sheet just behind your box? PVC, two TEEs, two 90s, and a hacksaw to cut it. No glue so you could take it down. Just thinking....

I was thinking the same thing. Just about any ammo you use will break glass if you happen to miss the catch box.
