Does a 40 foot shipping container full count as too much?

Joking aside, too much ammo is the stack of it you saved for the end of the world and died on top of because you didn’t use it to train. Admittedly, my stack of rifle ammo is far larger than my stack of pistol ammo, but I figure if I need much pistol ammo, i must be the luckiest SOB ever.

Anyone else find that skills with a pistol tend to degrade faster than rifle skills when you neglect training? I burn more pistol ammo than rifle ammo for this reason.
