This is a 100 Round 22lr ammo box. It has a locking sliding cover. It is compact and you can fit 14 of them in a standard Plano 131200 box. Check out my other ammo boxes for similar designs.
I will post them this weekend. Please let me know if 40S&W and 357sig works well in them. I can print them, but do not have any rounds to test. I will also post 45ACP.
This works perfectly and does just what it's supposed to do. I ended up taking out the internal piece just cause they are small shells but it's perfect and durable
