Vitavouri powders are all temp stable. The 100 is single compound . The 300 is pistol powdera, the 500 is a double compound mix.
The powder you are listing was formulated for 50 bmg. It is one of two such powders by vihitavouri
I use it frequently in the 33XC and the 37XC with the heavier bullets, especially the longer Badlands. It is very stable and consistent when I use it. I've often wished I could buy it in larger containers than the 8lb. size!
