I've got a couple of Orca cases that I use to transport my Bolt Action army to my friend's house on occasion, taking advantage of the strap that makes the box into a carry case. I drop it in a simple tote bag with a few extra bits and bobs for gametime (rulebook, dice, and those always pesky pin markers) and off I go.
Pro Tip: Don't leave a tote bag on the floor if you own cats.
Pro Tip #2: If you do leave a tote bag with your Orca cases full of painted minis on the floor, make sure you're using these troop targets and magnets. When one of my cats finally managed to tip the tote over with my army inside, *ONE* miniature out of lot "fell" from it's appointed place. Don't worry, Big Red! It wasn't a failure on the part of the case! It was one of three miniatures on a "team" base. The team base was magnetized and sticking to a troop target like a champ. I failed to properly seat the mini in the team base. The good news: No paint jobs were harmed in the feline free-for-all!
