On the draw-length side, the data shows that higher performance bows (faster) have a slightly larger increase/decrease in arrow speed per inch of draw length than the slower bows.
Does draw length affect arrow speed?
The longer your draw length, the longer your bow’s powerstroke will be – and the faster your bow will shoot. As a general rule, 1″ of draw length is worth about 10 fps of arrow velocity. Bows are IBO Speed rated at 30″ draw length.
How much does draw length affect speed?
The longer your draw length, the longer your bow’s power stroke will be – and the faster your bow will shoot. As a general rule, 1″ of draw length is worth about 10 fps of arrow velocity.
Does higher draw weight affect arrow speed?
Draw weight is a measurement of the force required to draw a bow. Bows with higher draw weights generate faster arrow speeds by transferring more energy to the arrow. The result is a flatter trajectory, deeper penetration, and greater likelihood of pass-through shots when bowhunting.
How much does draw weight affect FPS?
Adjustments: For every inch of draw length under 30″, subtract 10 fps. Every inch over 30″, add 10 fps. For every 3 grains of total arrow weight above 5 grains per pound of draw weight, subtract 1 fps.
How long should my arrows be for a 28 draw?
If you’re a 28-inch draw length and want an arrow that ends at the front of the riser, your arrow length would be around 27 inches. However, your arrow length can be longer if you need to weaken the spine of your arrow. For safety reasons, your arrows shouldn’t be cut too short.
How long should my arrows be for a 27 inch draw?
The arrow must be 29″ in length and supported by two points, which are 28″ apart. The number of inches the arrow deflects or bends due to the weight, is the spine size or measurement of an arrow. DYNAMIC spine describes the way an arrow reacts from the stored energy of a bow as it is shot.
How do I increase my bow speed?
5 Tips To Make Your Compound Bow Shoot Faster Increase Draw Length. When you draw the bow farther, you store more energy. Increase Poundage. If you do not overburden yourself and you boost poundage, penetration and speed are increased. Use A Smoother Trigger. Change Your Arrows. Upgrade The Cam. Conclusion.
Is 320 fps fast for a bow?
Even with today’s small profile, fixed-blade heads, most experts recommend a maximum arrow speed of 260-270 fps. Beyond that, broadhead planing becomes problematic for all but the very best archers. Today’s fastest bows are awesome in their ability to deliver speed.
What affects bow speed?
The longer the draw length, the longer the effective powerstroke. This factor, as well, will make the bow propel the arrow faster and more powerfully. However, the downside to a short brace height (5 to 6 3/8 inches) is that it can be more difficult to shoot.
What draw weight should I get for a compound bow?
A Beginners Guide to Buying the Right Bow in 3 Simple Steps Archer Weight Approx. Draw Weight (Compound Bow) Small-Frame Women (100-130 lbs.) 25-35 lbs. Medium-Frame Women (130-160 lbs.) 30-40 lbs. Larger-Frame Women (160+ lbs.) 45-55 lbs. Small-Frame Men (120-150 lbs.) 45-55 lbs.
How fast does a 40 lb bow shoot?
The nock attaches to the string and when you release the string, those 40 lbs are set free. The string launches the arrow forward and transfers the energy from the string to the arrow, which is now travelling at around 240+ fps.
How much does bow draw weight affect arrow speed?
Dropping your bow weight by 10 pounds will reduce your arrow speed 15-20 fps. Said in a slightly modified way based on our results, “You will lose approximately 20 fps for every 10 pounds of draw-weight reduction.” 2. For every inch you reduce your draw length, you will lose roughly 10 fps of arrow speed.
How fast is a 60 lb compound bow?
So assuming we have a bow rated 320 FPS IBO speed, an if you have a 60 lbs. version of the bow set to 28″ draw length, with some accessories on the string, a 425 grain arrow would deliver approximately 59 ft-lbs of kinetic energy at point-blank range.
What is the fastest compound bow on the market?
Blackout Epic. The Blackout Epic is a quality compound bow with a top speed of 340 FPS. There are two models of the Black Out Epic with the adjustable draw weight. The first model is for a range of 45-60 pounds.
How important is arrow speed?
Raw speed is derived from harsh draw-curve cycles, but it more directly translates into lighter arrows. Speed is important for 3-D archery when shooting at unknown distances or to provide wider margins of error in wide-open places, but it is less decisive in a whitetail context.
What size arrow do I need for a 29 inch draw?

What happens if arrows are too long?
If, however, by being too long, the arrow’s dynamic spine is too low, then the arrows will not be accurate as they will tend to “fishtail” in flight. They will also tend to fly to the right (for a right handed archer).
Whats the shortest you can cut an arrow?
Arrows that are cut too short can be drawn past the arrow rest which could result in the arrow falling from the string, jamming, or otherwise causing damage to the arrow or the bow, and could even lead to personal injury. Never shoot an arrow that is less than one inch past the arrow rest at full draw.
How many grains is a 500 spine arrow?
