AH, Don't let a few spine shots convince you of a loads abilities! I'm not knocking the lightfields here, in fact never used them, but being a bow hunter also, I can drop a moose in his tracks with a spine shot! You need to evaluate a loads performance on thehits to the boiler room.The 30 yd. double lung hit is the good hit! If ashot is well placed, double lung, shoulder, and brings thequarry down in a reasonabledistance then the load stands as a good load in my book. I'm fine with the 30-50 yd. run after the shot.I don't careif the load breaks apart, in fact this may provide for more internal damage in some cases. As long as the end result is a dead deer, then all is well!
