Outdoors Insider, with Dale Sunderlin: Bad guys DALE SUNDERLINStar Beacon So, if you’re interested, here is what works for me.
Short shafts I usually cut my arrows as short as is safe. My personal preference is to have the arrow cut about one inch in front of where the arrow contacts the most forward portion of the arrow rest. Now, I have to be careful though. I don’t shoot a bow equipped with cams that incorporate hard walls, so the chance of overdrawing the bow and pulling the arrow past the rest and off the string is very real. If you shoot a cam with a soft wall, or you’re a finger shooter, you have to be more careful as your draw length will vary. This could result in drawing back farther than normal under certain circumstances. Under these conditions, until you’re more consistent in your draw, you may want to go a little longer. Two inches of arrow overhang might be a better recommendation to prevent the arrow from coming off the string at full draw. Speed kills A couple of reasons why I prefer a minimum arrow length are increased velocity and more maneuverability. When it comes to velocity Jim Retalic over at Sports Junction told me something a long time ago that has stuck with me ever since, “Speed Kills”. First, let me explain the increased speed, as it is two-fold. When you shorten up an arrow, consequently you stiffen its spine. By doing this, you would hypothetically drop down one spine size and shoot lets say a 20XX as compared to a 21XX, now in carbons that would be 340 spine-sized arrow, which has a lighter mass weight or grains per inch (gpi) than a stiffer 300-spine size. (Note: stiffer spine sizes require more material to make the arrow stiffer, which increases the mass weight.) Shooting a 2013 and trimming 6 & 1¼2 inches off it, down to 26 inches, at 9 gpi, will reduce the total weight by 54 grains to a bare shaft weight of 234 grains. While in carbon shooting, a 340 FMJ at 26 inches and 11.1 gpi would drop your bare shaft arrow weight to 288.8 grains, saving you about 72.2 grains. Depending on fletching, insets and your choice of broadhead, with all of their weights combined, you would most likely end up with a finished arrow weight of around 325 grains aluminum or 425 grains carbon, in turn, giving a flatter shooting arrow. Tipped with 100-grain insert/broadhead combination, my 26-inch Easton 2013s weigh in right at 325 plus or minus a few, providing the accuracy and penetrating power I need. These arrows zip out of my bow at blistering speeds and give me enough kinetic energy to tackle almost any big game in North America. Maneuverability
