I also saw the 80+ degree pressure spikes. What I have not tested enough yet to know is if you drop down say 1.5 grains will the accuracy hold in hot weather or will it still get wonky? In some loads if you have to reduce them 1-2 grains then whatever velocity advantage R26 has may go out the window.
Will keep the ammo with the beer until I work up some R16 & R23 loads.
