maytom,

I did some testing between the Shockey's Gold powder(3f) and Triple Seven this week in my T/C Omega. I'm pleased with the Shockey's Gold powder as it seemed to be a little cleaner than 777 and grouped well in my rifle. I did not have a chrono with me as I would have liked to compare the velocities of the two. One thing I will recommend to you if you are considering Shockey's Gold, is to getit in 3f. I shoot 2f Triple Seven and it is quite a bit finer than the 3f Shockey's Gold, so 2f Shockey's Gold would more than likely be extremely course. In fact I have heard it described as "rock salt."
