It seems silly to have 5000 rds of any ammo if you can't take it with you ... and thats a lot of money tied up in one thing.
Seems prudent though to have 500 - 1000 rds ... at least in the weapons you are likely to grab-n-go with. More for the .22 since its so small and inexpensive.
Given the funds ...I'd love it to all be something like Cor-Bon DPX since that stuff performs so well ...but in the grand scheme of things ... one should be able to get by with any quality product.
And hey ...if you are gonna take a gun ...it should have ammo, otherwise its really just an expensive rock.
