I take my speed/efficiency setup to Sherwood forest every year to test bows during their annual Jubilee. Last year and the year before, Mathews bows could not be topped for speed, efficiency. This year it was BowTech. The assassin and Destroyer were very impressive. I have always thought the Bowtechs were the quietest and that has not changed. The top 3 fastest bow were all Bowtech with one destroyer set at 69 pounds with a 6 grain per pound of draw arrow using a 100 grain tip sent an arrow at 312 fps. When we tried a 75 grain tip, he was 327 FPS. A 220 grain head produced 285 FPS and got 81 foot pounds of KE.
As in most years, people are shooting on the low side of arrow weight (between 5.5 to 6.5 grains per pound of draw weight) There were a few guys in the 8 and 9 grain range and they consistently had the quieter and more efficient setups. Again, everybody coming through the door insisted they have to shoot 100 grain heads and that 125 is way too heavy. (advertising is powerful) after experimenting with 75, 100, 125, 150 and 220 grain heads they understood that their KE, momentum and efficiency (penetration) went way up with an increased tip weight as did their FOC (which equal better flight stability) with little loss in speed, they started to rethink the 100 grain broadhead market and began thinking heavier.
I tested 82 different bow setups in the two days (up from last year) and asked everyone what broadhead they planned to hunt with. There was a noticeable change in head choices. Last year, everybody said Rage. This year, Montech and Muzzy were the most mentioned. This year, people seemed more prepared and nobody hit my chronograph.
