Do you still have room in the storage locker? Then you don’t have enough.
Moved my daughter out to college and we took her shotgun and ammo to the police storage area. I had a bin about 2’x2’x 3’ of shotgun shells for her figuring it would last awhile at the nearby trap/skeet place.
I apologized to the cop as we tried to move it.
“No problem - this is maybe two days at the range around here!”.
A couple years ago I bought my wife her first pistol along with 300 rounds of self-defense ammo and 1,000 rounds of target ammo. I should have doubled the good ammo and tripled the target stuff.
