Ammo box for 50 rounds of .22LR

UPDATE: 
 

There have been comments saying the holes in the insert were too small, so I went back and made an insert with bigger holes. 
I have tested this over several prints, and all had a loose fit.

The sliding lid makes it easy to tip 5 shots at a time in your hand to load the magazine

I find these very useful when doing competitions.
