What I was referring to is the temperature sensitivity of the powder. The temperatures between the time I have for testing and actually using could be as much as 60 or 70 degrees.
I ran some wolf over the magnetospeed this just now.
Its colder than hell, 31* according to my weather station, so I took the 20 out front and put a few rounds through it.
Wolf steel case, 31*, 20 group buy barrel
2600 FPS, SD 25fps
Wolf steel, 50*, 20 group buy barrel
2622 FPS, SD 20.5fps
Itll be near 80* by Thursday so Ill get some more data then.
Have to love western Oklahoma weather lol.
Edit: hell if it stays in the 1 FPS/degree range its better than A2520.
