This is an updated version of my other 9mm ammo box. I changed it to a more standard size of 50 rounds with 10 rows of 5 rounds. I angled the bullets at a 45 degree angle to make them easier to to take out. The bottom can also sit inside the lid which makes for a smaller footprint at the range. It can be a little difficult to get the lids off and on at first but gets easier over time.
