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 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.
Is 70 lb draw too much?
For example, a bow with a 70-pound peak weight and a 80% let-off should have a holding weight of around 14-pounds. Being able to hold a bow at full draw for 30 seconds is great, but if you’re shaking, struggling, and exhausted at the end of that time, then you’re not going to be able to make an ethical shot.
How many FPS do you lose per pound of draw weight?
On average you will gain or lose 2.4 fps per pound change in draw weight. If you go lower you will lose, going higher you gain.
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.
Do heavier arrows fly better?
Momentum. Oftentimes proponents of lighter, faster arrows point to the arrow’s kinetic energy as support for their preferences. But the benefits of a heavier arrow don’t just stop with better penetration. Heavier arrows reduce stress on your bow and typically produce a quieter shot than a lighter arrow.
How 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.
What draw weight do most hunters use?
Some shooters are capable of shooting 70, 80 or 90lbs, but most adult males shoot between 60 and 70lbs. Today’s bows are extremely efficient and 40lb compound bows are more than capable of harvesting many big game animals. For whitetail deer hunting anything above 40 lbs is fine.
How far will a 50 lb bow shoot?
How Far Can a Bow Shoot? | Ranges by Draw Weight (With Chart) Bow Type Draw Weight Effective Range 40 lbs 50 – 60 yards Crossbow 80 lbs 30 – 40 yards 150 lbs 40 – 50 yards 200 lbs 50 – 60 yards.
What should my draw weight be?
Build, Bodyweight and Suggested Bow Draw Weights Type of Person/Build Weight (lbs) Compound Suggested Draw Weight (lbs) Large/Strong Child 100-130 25-35 Small/Slight Woman 100-130 25-35 Average Woman 130-160 30-40 Large/Strong Woman 160+ 45-55.
Does a shorter draw length affect arrow speed?
With more potential energy in the drawn bow, there will be more kinetic energy in the released arrow – more arrow speed. As you lengthen your draw you must go to a longer and stiffer arrow for the same maximum draw weight.
What is a good arrow speed for deer hunting?
Even with today’s small profile, fixed-blade heads, most experts recommend a maximum arrow speed of 260-270 fps.
How can I increase my arrow 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.
Does draw weight affect accuracy?
Arrow accuracy can be effected if the draw weight is increased as an arrow’s spine needs to be matched to the draw weight. If this has been done then the arrow matches the bow. A significant increase in bow draw weight will mean that the existing arrow no longer matches the bow.
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.
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.
Is a 500 grain arrow heavy?
For reference, light arrows weigh about 350 grains, a typical arrow weighs 420 to 500 grains, and a heavy arrow weighs over 600 grains. Bentcik said few Americans use arrows weighing 700 grains or more unless they’re shooting traditional equipment.
Does arrow weight really matter?
Arrows come in three weight categories: light, midweight and heavy. Lighter arrows fly faster and can group more tightly, but they’re often harder to tune. Heavier arrows fly slower but resist wind better and penetrate deeper. Shooting the wrong arrow weight for a bow can damage equipment and harm the archer.
What grain of arrow should I shoot?
If you want to target practice, you want the arrow to weigh in total (shaft, vanes, insert, nock and field point combined) around 5 to 6 grain per pound of draw weight. So if your bow has 60 lbs. of draw, you want to use arrows that weigh in total between 300 and 360 grain.
How long should my arrows be for a 29 inch draw?
it depends on the arrows you choose, you need at least 1/4″ of arrow overhang on the rest. so you can probably shoot an arrow that’s about 28 1/4 for rests that are set up normally. and go all the way up to full length 36″ arrows for indoor. i would suggest 1″ of overhang on your rest.
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.
Does draw weight affect draw length?
The draw weight is marked on the bow’s lower limb with the pound sign (#),such as 35# @ 28”. That translates to 35 pounds of draw weight at a 28-inch draw length. A compound with a 50-pound draw weight at 28 inches will remain at 50 pounds if it’s adjusted to a 26-inch draw length.
