60rd 22LR Ammo Box for Revolvers

I was asked to make a 60rd ammo box by a revolver shooter, so they could slide back the lid and drop 6 rounds out instead of 5. So, I modified my previous 22LR ammo box to hold 60 rounds in 10 rows of 6 rounds. I also modified the lid groove to (hopefully) make it more robust. While I did not have an issue, some people contacted me and let me know that the rails on the box was a weak point, so I make it a bit thicker by modifying the design.
