    Does anyone know if there is a table or list that shows what powders are temperature sensitive or tolerant as the case may be? [​IMG]

    Don't really know of a listing but, most of the slow burning "Ball Poders" like H870 and WC872 are heat sinsitive. As chamber heat rises, you may develope a flyer or two out of a 10 shot string.

    This is found more so in hot weather. In the winter time when temps are low, the chamber and barrel heat rises slower and the problem normally is not seen at all.

    It's a great winter time powder and I use it in all my big mags from the 6.5/300 Weatherby up.
