Quick Answer: Do Heavier Arrows Fly Better?

Are heavy arrows more accurate?

All factors remaining equal, heavy arrows always are more reliable, more durable, than lighter.

This has nothing to do with kinetic energy (a poor measure of arrow performance on game) but momentum (which leans more heavily on mass than velocity)..

How much does arrow weight affect 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.

What is a good arrow weight for whitetail?

Overall Arrow Weights I think a good average hunting arrow should fall in the 6 to 8 grains per pound of bow weight, with lighter bows maybe even closer to 9 to 10 grains per pound. A typical 60-lb. bow should be in the 360- to 480-grain range, a 70-lb.

What happens if your arrows are too long?

It can’t hurt if it’s too long if it’s shoots well for you. Too long and you have to have more spine which adds arrow weight, more fletching, and heavier tips for proper FOC (arrow balance).

What happens if your arrows are too lightly or heavily spined for your bow?

Every arrow shaft has a degree of stiffness called spine, which is its resistance to bending. … If your arrows are too lightly or heavily spined for your bow, the “archer’s paradox” movements will be extreme, resulting in poor arrow flight and loss of accuracy.

Are 340 or 400 arrows heavier?

340 arrows are stronger/stiffer/harder in “spine” than 400 arrows because they bend less. 400 arrows are stronger than 500 arrows. … A weaker arrows is “softer”. Generally 600 arrows are for bows from 15–35 pounds in draw weight, 500 for 35–55 pounds, 400 for 55–75 pounds, and 340 for 75–95 pounds.

What does 400 mean on an arrow?

The numbers refer to the spine of the arrow. The different spines refer to the stiffness, a 400 spine arrow is generally for bows 40-60 lbs. 350 spine is for bows roughly 55 – 75 lbs, and a 500 spine arrow is for bows roughly 30 – 50 lbs.

What happens if my arrows are too stiff?

Too stiff an arrow usually just slows the bow down with a heavier arrow. Too weak a spine arrow usually yeilds a faster lighter arrow. But the light spine cause the arrow to shoot way off the mark as the range increases.

What is considered a heavy hunting arrow?

There are basically three shaft weight categories: light, mid-weight, and heavy. … A mid-weight arrow weighs between 6.5 and 8 grains per pound of draw force (455 to 560 grains for a 70-pound bow) and a heavy arrow is anything weighing over 8 grains per pound of draw force (more than 560 grains).

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. This is where the broadhead comes in.

How do you tell how fast your bow shoots?

To calculate arrow speed, measure the distance in inches between the two groups of arrows you shot from 20 and 40 yards. Granted, this is not as accurate as a chronograph, but it’ll give you an idea. Once you have this figure, you can calculate the kinetic energy produced by your bow.

How heavy should my arrow be for elk?

420 grainsFor elk, I recommend a finished arrow weight of 420 grains as a minimum for hunters drawing 60-70 pounds. Although bows are becoming more efficient and lower-poundage bows are capable of taking down big game, higher poundage will certainly help you on large game animals.

Is a heavier arrow better for hunting?

Heavy arrows penetrate better. The first reason why it’s important to choose the best hunting arrow is because once an arrow leaves the string it ceases to be propelled. … That force has a greater effect on the faster arrow (see Newton’s Second Law of Motion) so it decelerates faster than the slower arrow.

How heavy should my arrows be?

As draw weight increases, so should arrow rigidity (spine). Also, we strongly recommend that you use an arrow with at least 5 grains of weight per pound or draw weight (if you are shooting a 60 lb. bow, you should use and arrow of not less than 300 grains). This includes your field point or broadhead.

Is a 60 lb bow enough for elk?

60 lbs is fine, you’re on the right track as far as arrow weight. get a strong razor sharp fixed blade to fly like a laser and he’ll be zipping through vitals.
