Doing recon for a new hunting load. I can’t develop the load in the temps I’ll be hunting so I’m using the most temperature stable powder I can find. Triple nickel (N555 from Vihtavuori) is the most stable I know of across temps. It also is very popular with top level f-class shooters. VV claims it was developed for 6.5 creed so I’m hopeful I will not just maximize velocity and consistency but temp stability as well. What are your favorite powders for extreme temperature spreads?
