That powder is in mass supply. I have had to come up with less then ideal loads using other powders. Accuracy is still there but performance isn't in terms of velocity. So I settled and save the food stiff when my A game needs to come out and play

It's temp stable. Not sure compared to others, but according to Hodgon it is

According to charts posted on this forum it's 1.68' fps per degree of temperature change, not exactly something to look forward to. I have 8 lb that I might have to use in a 6.5x300 Weatherby if better choices don't come back in stock
