The temperature sensitivity issue is not just the risk of excessive pressure but also change in point of impact. Even if you reduce the load so that pressures are safe at high ambient temperature you may still get a significant change in point of impact. Enough, with my 17 Rem to completely miss a rabbit at 150 yards. The ADI powders are a lot better, in my experience and we can always get them in Oz which can't be said for other brands.
