I have used .45 Schofield Cheyenne Cartridge boxes with labels glued on with rubber cement. I use 45 Schofields in mine as a "44 Henry duplication load", so the boxes work great.
I had some really nice labels I made in the past, but have no idea what I did with the JPEG file. This one I just cobbled up, and resized to 5" by 2 1/2". The first one is the one I used, but the other two are also re-scalable.
