I am looking to try some CFE Black in the x39 using bullets from 125 to 160 gr. Seems like this powder makes good velocity with acceptable pressures. I have had good results with Reloader 7 and pretty good results with Accurate 1680. Looking at the testing Larry has done, Leverevolution appears to be the one to beat with heavier bullets. Its time to buy powder and am looking for anyone that has tried the CFE Black with the lighter bullets.
