IMR 7828ssc

[jayran]

I went shooting yesterday runiing test loads thru my 7stw with some 7828ssc, and had one 5 shot group measured .6 and the velocity was 2805,2805,2812,2805, 2809 I have never seen velocities so close! My big question is how stabile is this powder to temperature?

I put it in the same category as the reloader powders or ball powders..... All over the place going from cold to hot. I bought four pounds and worked up a great load before I figured it out.
