"How many is just plain too many?"
Anything over one box per weekend between loading sessions. Otherwise you're going to the range for a 'spray and pray' party without concentrating on accuracy. ??
I agree that high storage temps will reduce ammo to trash. Anything in the 300F and up range would damage it in a month or so. But ammo can take any temp you can take and do it for a few years without significant change. I still have some reloads I made in the mid-60s that have been stored in my open garage and it functions quite well (when I try it at all).
