I looked around for an answer, but can only find information pertaining to ammo reliability in defensive firearms, not accuracy.
I'd like to keep a box or two of some Winchester Power Point hunting ammo out of direct sunlight under my seat in my vehicle in case I forget to bring ammo when I go hunting. The ammo would be allowed to reach ambient temperatures before being shot.
Various sources say that reliability shouldn't be an issue. What I'm far more concerned about is the extreme heat decreasing accuracy. I wouldn't notice a minor increase in group size, but would like to keep my groups around an inch or so, which I already achieve with fresh ammo.
I live in a subtropical environment with long, hot, humid summers and winters that occasionally dip into freezing.
I would prefer not to have to worry about rotating the ammo out; the ammo very well may stay in my vehicle for several years without being touched.
Does anybody have any experience with leaving ammo in a vehicle for long periods of time? Should I be concerned with a decrease in accuracy?
