What is the difference between 340 and 400 arrows?
The difference is in “spine” or the bendiness of the arrow.
A 340 spine arrow is stiffer (more resistant to bending) than a 400 spine arrow.
When arrow tuning, for arrows of the same length, 340 arrows may tend to pull left (an indicator of Too Stiff) while 400 arrows may tend to pull right (an indicator of Too Weak)..
What arrow should I shoot?
The first variable you need to look at is draw weight. 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).
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.
How long should my arrows be for a 29 inch draw?
Static spine To calculate this, arrows must be 29” long and supported at two points 28” apart. The number of inches the arrow bends multiplied by 1,000 is the arrow’s spine. So, an arrow numbered 350, bends . 350” when the weight is applied.
What is the difference between 400 and 500 arrows?
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.
How heavy should my 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.
Is an arrow as deadly as a bullet?
An arrow is as deadly as a bullet, so the basic safety rules that govern firearm shooting also apply to archery. Although shooting accidents are rare among bowhunters, they do happen. Archers must obey a few common safety rules, whether on the range or in the field.
How do I know my draw weight?
Draw Weight Recurves and longbows have incrementally heavier draw weights the farther they’re pulled. The standard for determining their draw weight is taken at 28 inches of draw length. The draw weight is marked on the bow’s lower limb with the pound sign (#),such as 35# @ 28”.
Do I need to cut my arrows?
The standard way to measure arrow length is from the back of the point to the throat of the nock. … 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. Your archery shop will make sure your arrows are the proper length.
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 do I know if my arrow spine is too weak?
A lighter tip INCREASES an arrow’s spine (makes it act more stiff). If the arrow is too stiff it will favor the left side while if the arrow is a bit weak, it favors the right side.
What is a 55 70 arrow?
55/70 is a spine number, though not really indicative, the spine of those arrows is a . 400 spine or near. With your bow, that spine should be just fine.
What does the number on an arrow mean?
A smaller number means that the arrow has a stiffer spine. … For example, 3-60/340 means three wraps of carbon-fiber with an aluminum core tube diameter of 60 and a spine stiffness rating of 340. Carbon arrows also are labeled to indicate their spine deflection.
What is the difference between a 300 and 400 arrow?
The word is SPINE, and there is . 1 inches difference in deflection between 300 and 400. Total arrow length and tip weight will determine what spine you need for which poundage you choose to shoot.
What does 400 spine arrow mean?
“Spine” is the measurement of the arrow’s flex or bend. Arrow shafts are sorted by spine measurements, and manufacturers designate them with a number. … Some common numbers are 350, 400, 500 and 600, but they vary by manufacturer.
