Hope that one repeats for you! My best-ever group with the 70gr Blitzking turned out to be a fluke, but I do have a load for the 87gr TNT that repeats great groups. Just picked up some 4166 to try as I work with light bullets in a .270, but will also try it in the .250 and .300 Savages as well as .204 and 6mm Rem. Interesting development of a "copper eraser" with resistance to changes due to temperature.
