Not very encouraging . . . . I have some 3F Shockey Gold - supposedly the same animal as APP. Have only tried it with one load - 200 gr. Shockwave (50/40) with 110 gr. in my Black Diamond XR. It initially shot very well. Got almost 2400 fps. Later I got some wandering zero issues that I now think were related to mylack of understanding oftheneed to not swab between shots. I may revisit this load sometime this winter when things slow down a little.
