Re: Hodgon Extreme Powder??
You are going to get alot of different answers and opinions on this topic. The reason for that is that it has more to do with it than just the temp sensitivity of a given powder. It can also depend on how compressed a load is, how much empty space is in a load, if the load is at max, under max or close to max, the burn rate and several of these issues combined in different configurations may cause different results in different temperatures. It is very hard to say. I will say this, H powders (extreeme) typically have the least amount of swing than other types for a GIVEN set of circumstances. That doesnt meen that if you are getting .5 FPS per temperature rise or fall that the next guy will with the same powder.
It is unpredictable at best untill you test you own loads.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
