A 50 cal can of 9mm is nowhere near 60 pounds. 25 at the very most.
The only downside to ammo cans, especially from Princess Auto, is the cost. $30 is too much. They are handy things though.
The MTM boxes work well, but so do the factory boxes. Depends on what and how much you're loading.
25 pounds at the most?
Let's do some math. According to your statement
5.5 lbs for the ammo can
124 grain bullets
1000 bullets equals 124000 grains.
7000 grains in a pound.
17.7 lbs of just bullets.
Plus 5.5
23.2 pounds
That's only for a 1000 rounds of 9 mm. Not including brass, powder weight is negligible.
Now. Fill up a 50 cal can of loose 9mm rounds and let me know how much it holds.
