How Much Does Arrow Weight Affect Speed?

Do heavier arrows fly better?

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..

How heavy should my hunting arrow be?

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. bow in the 420- to 560-grain range.

Can you kill a deer with a 35 pound bow?

That’s not to say shooting adequate poundage isn’t important when bowhunting — it is, but primarily because it’s a large factor in the amount of kinetic energy a bow and arrow setup can produce. … But, a skilled shooter with a 35-pound bow is very likely to kill a deer when shooting at it from 10 or 15 yards.

How long should my arrows be for a 29 inch draw?

While most people go for 27.5-inch arrow length for a 29-inch draw, a beginner would be happier with a longer arrow. While this offers less power, it is considerably easier to aim with. If you need extra help, you could consult this handy arrow length to draw length chart.

Does more 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 fast does a 50 lb recurve bow shoot?

183 fpsWith a 550 grain arrow my 50 lb bow shoots 183 fps with a fast flight string which I have shot for years with no problems. A 45 lb bow would lose probably 7-10 fps. You could make that up with a lighter arrow.

Does arrow speed matter?

An arrow that is moving faster will carry more kinetic energy than an arrow of equal weight traveling slower. This means better penetration upon impact. However, any modern bow shooting a relatively heavy arrow will have good penetration.

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 your arrows are too lightly or too 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.

How fast does a 50 pound bow shoot?

Your bow only IBO’s at 300 and you are shooting 20lbs lighter with 2″ shorter draw and a 50 grain heavier arrow with a kisser, peep and D-loop on the string. I lose 40 fps with my setup and I shoot 70 lbs and 29 inches with a lighter arrow, you almost have to lose 90-100 with your setup.

What happens if arrow spine is 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.

Is 280 fps fast for a bow?

Actual Velocity That alone will usually reduce the speed to 325 to 330 fps. … Set your bow to 60 pounds instead of 70, and you’ll likely land in the 300 to 310 fps. Of course, shooting a 400-grain arrow will reduce your speed well below 300 fps, likely in the 280- to 290-fps 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. This is where the broadhead comes in.

How many FPS do you gain per pound of draw weight?

2.4 fpsOn 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.

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.

How long should an arrow be for a 28 inch draw?

around 27 inchesIf 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.

What should my arrow FOC be?

The best FOC for hunting arrows ranges between 10-15%. Larger FOC arrows will carry with them more power and penetrate better than those with less FOC.

How much does an arrow drop at 40 yards?

It can be seen that the arrows start at just about four inches under the line of sight, rise above the line of sight, then drop down to be even at twenty yards, the dead-on sighting distance. At 30 yards the fastest arrow has dropped just over 2″ and at 40 yards it has dropped over 7″.
