More load testing with my Larue Stealth

10-11-10 Chrono testing and accuracy with Vitavory N140.

(I have wanted this powder for a while but its made from unobtainium meaning I could never find it in stock until a few days ago at the Sportsmans warehouse. They only had 1 pound)

I like this load the best its 100 fps faster than my accuracy loads with N135, Varget, and H335 and its still very accurate.
