Go for Goats, A Bow for Goats
by Darren Choate
Having accumulated 16 points, I was confident I would draw, but until the official results are out, you never know for sure. After 14 years of applying, I finally drew an archery antelope tag in Arizona. With most of spring and summer to prepare, I went to work with the goal of putting together a bow/arrow combination to propel an arrow at 300 FPS. The caveat, I shoot 60 pounds–because of a bad shoulder–at 27.5-inch draw length. After researching new bows, I chose the Mathews Halon 6, which has an IBO rating of “up to 345.”
To begin the process, I used our Arrow Speed Estimator to find out my effective speed. I knew I could come up with an effective speed of over 300 FPS with the 60-pound Halon, but I wasn’t sure where I would need to be regarding arrow weight. My effective IBO speed–for 60-pounds, 300-grains–calculated at approximately 312 FPS. To find the most efficient arrow weight, one that would have enough energy to take an antelope at distance–hopefully less than 75-yards–I entered my data into our Arrow Efficiency Calculator. I shot an IBO arrow at just over 315 FPS, which estimated that I could shoot a 315-grain arrow at approximately 310 FPS, which had plenty of energy to get the job done on antelope-sized game.
Finally, I used our Arrow Weight Estimator, to search for the perfect arrow, and chose the Easton Hexx. At 60-pounds and approximately 27-inches, the perfect spine was 400, which weighs 7.2 GPI. My completed arrow, with 75-grain Wac’Em, weighed-in at 315-grains. To complete the project, I fired a group of arrows through the chronograph, with the average of 309 FPS. Again, I entered this data back into the Arrow Efficiency Calculator to check my approximations, and was pleased with the following results.
- Mathews Halon 6 | Easton Hexx/400 | Wac’Em 75-Grain Fixed
- Speed: 309 FPS
- KE: 66.72
- Momentum: .4318
