You are probably fine. However, I would keep all ammo in a more temperature-stable environment, if possible.

I had a bad experience with ammo stored under heat. In about 1961 I loaded some .30-06 ammo using military cases. The powder was 3031 powder that had been stored in an attic. In 1977 this loaded ammo was stored in another attic and when I got back in 1985 I fired some of this ammunition. It fired well, but I started to notice what appeared to be partial head separations. The load were not high pressure and I could not figure it out at all. Then I got a head separation that blew gas back into my face. I stopped shooting and took a good look at the cartridges. I show blue corrosion marks. I stuck the bullet of a loaded round to loosen it from the case to inspect the powder. The case broke in half. It appears that the poweder had broken down or deteriorated releasing acid like materials resulting in weaking of the bass case. We are talking about many years of heat followed by cold winters.

That sounds like damage from the cases having had mercuric primers fired in them at one time or another.
