Working Up Load with Power Pro Varmit PPV

[mel]

I saw some good results with PPV at moderate temps, but I saw a really big pressure spike (gained 200 fps) going from 80 to 90 degrees.


Here's a link to a thread on that powder: http://www.65grendel.com/forum/showthrea...ults/page3

thanks ill keep an eye on it when it starts to warm up , right now its 40* out ,but in the summer it will get to 100+ here so ill check the loads with every 10* temp rise when it starts to warm up
