Broke out my pro chrono pal and shot my 340 through it with 2 different arrow weights. The bow is set a 29.5 inch draw, the draw weight on birth certificate indicated 71.3 max, however, the dealer backed off max just a touch and the best I can determine the bow is pulling just over 70 pounds (70.2 according to easton digital scale). The first arrow had a total arrow weight of 358 grains. 5 shots through the chrono varied between 327 and 328 fps. The second arrow weight was 443.5 grains. 5 shots with this arrow produced a reading of mostly 296fps and 1 shot at 295 fps. I weighed the arrows with my grain scale and the weights are very accurate.
