Yeah, 335 can definitely get touchy in hot weather, especially when shooting prairie dogs or other small rodents. I used to run it all the time, but also found it dirty-burning, though it may have improved since then. When TAC appeared I switched over, as it's very clean-burning and about as temp-resistant as any powder made, at least in my tests. Benchmark is also great, as it's about the fastest powder for bullets in the 40-55 grain range, and also clean-burning. It's extruded, but has very small granules so meters fine.
