The anonymity of today's arrow

The anonymity of today’s arrow

With the advancements in technology today the arrows are amazingly well engineered each manufacturer has its own style and spin on the manufacturing process with there products. when I first started shooting arrows I went to Cabelas and bought the standard 12 pack of carbon hunter arrows I bought some field points in 125 grain and then I also bought some broad head when it came time to hunt.  had I known what I know now I would have never purchased those arrows. it’s not because they were bad, they were perfect for my ability at the time. I didn’t know much about arrows and the anatomy of them and looking back I wish I had done some research before making the purchase, because now I shoot bullets…

I have researched quite a bit and have been shooting much more, I would like to pass along the information that I have learned to you to share and make educated buying decisions. strictly speaking there are various types of arrows, products range from different materials and different stiffness’s also known as arrow “spine”. Personally I enjoy shooting carbon / graphite arrows the reason for this,  is the weight of the arrow is much lighter and can translate into speed when being shot from a compound bow. There is a hybrid arrow made by Easton called the full metal jacket (FMJ) this arrow is a carbon then wrapped with aluminum strands to make it stiffer as well as more durable. the drawback to this hybrid is its weight but that translates into a lot of kinetic energy and that translate into bone crushing power.

today I will be talking about what I shoot personally, as well as what a female Archer who is looking for a hunting arrow would shoot.  Having shot Easton axis arrows, cabelas carbon hunter arrows, maxima red arrows. I’m going to have to honestly tell you the Black Eagle carnivores are by far the best hunting arrow I have ever shot.

You’re probably going to say “why do you say that? ”

the biggest reason is they shoot night and day different from any manufacturer that I have shot plus the manufacturing process and product quality. They are easy to build and tune. This is arrow anonymity, I hope this is a good guide for you to use.

Terms you need to know – and what they do for YOU

  • Arrow final weight = total arrow weight in grains (some states like Washington state require you to make min 300 grains , or 6 grains per lb of draw weight what ever is higher!)  (example 6 g x 70 lbs draw = 420 g final arrow weight 6 g x 60 lbs = 360 final arrow weight)
  • Nock bushing = small hollow aluminum bushing to protect the rear of the arrow. (it fits between nock and arrow shaft)
  • Pin bushing = small aluminum solid pin Bushing. (it fits between nock and arrow shaft)
  • Pin nock = open-ended and hollow knock to be slid on top of pin Bushing then other end attaches to the string
  • today’s arrows use plastic veins instead of the traditional feathers to help stabilize the arrow during flight.
  • Vein = thin flexible plastic that is glued near the end of the arrow to help aid in flight
  • Helical veins = veins glued onto the shaft with a twist in them To promote rotational spin
  • Nock = usually made out of plastic and inserted into the back of the arrow this is where your string connects
  • Insert = aluminum or brass piece that is glued into the front of the shaft where the tip is screwed into.
  • arrow wrap = usually made out of self adhesive vinyl material that is stretchable to wrap around the end of the arrow before the veins are glued or applied to the shaft.
  • Field Point= practice tips that you would use for archery.they screw Into the insert
  • Broad heads = extremely sharp and dangerous used for hunting they screw onto the tip in replacement of field Points.
  • Spine = The amount of flex in the arrow
  • Straightness = the building block of the arrow – how straight from the manufacturing process the arrow is.   .001 is the best = most are .003 to .015 !!!!

F.O.C.  = Front of Center balance point.

This measurement results from the relative weights of the components used in / on the arrow: shaft, insert, head, fletching, and nock.  F.O.C. value range of 7-15 % is widely used as the best for a good balance between arrow range and arrow flight stability. If your calculated F.O.C. doesn’t fall with this range, don’t stress out. You can still have good arrow flight with an F.O.C. as high as 18 percent, but your range will not be as good. Try not to go below 7 percent.

Weight: If you’re concerned about your finished arrow weight or your F.O.C. balance it’s worth mentioning that your choice and size of fletching material will have a significant impact on both of those attributes.  Since all of that weight is going to be concentrated in the rear of the arrow, heavy fletching material means a you’ll also need more tip weight to maintain a good F.O.C. balance.

What should you be looking for?

It is generally agreed that the optimal F.O.C.% balance for an arrow is somewhere between 7% and 15%. In the example on the above, the 30″ long arrow has balance point that is 3″ forward of the arrow’s actual center (15″). So it’s F.O.C. is 3/30 or 10% – a reasonable F.O.C. balance.

how to figure out a F.O.C. you can do this 2 ways; manually or with a Calculator = just use the calculator it’s much easier

Here is a black eagle Carnivore built for me shooting a 28″ arrow with my bow pulling 50 lbs and using pin bushing, and pin nock with 100 grain field point  this foc translate into 10 percent FOC and 80 ft-lbs of Kinetic energy from my Hoyt Carbon spyder turbo

What I shoot now – Black eagle ultra lights

 

This is what a shorter arrow should look like – you can see here the arrow length is 25 inch for a draw length of 22 ~ 25 inches black eagle carnivore ULTRA Lights shooting out a Hoyt Ignite

Womanssetup

For a smaller draw length 22″ to 25″  ** with a 20 grain insert to make min weight for WA state hunting regulations

How much Kinetic energy do you need? here is a good guide to go by – between 25 and 65 is great for all big and small game.

I use Flex Fletch  the model is FFP-360 it’s a 3.6″ Vein weights 8 grains and is pictured in the photos above – they are the best stable veins I have ever shot. at long distances 50 ~ 100 yards you will notice and witness stability never before achieved. They come in a verity of colors too.

Helical veins = plastic veins installed with glue with 3 to 4 degree offset, Helical veins are by far the best when installed properly they add Rotation to the arrow during flight stabilizing it though the air and at longer distances like 50 to 100 yards it becomes very noticeable.

Helical

 

 

Plastic Fletching: This fletching is made from soft plastic or vinyl and is often called vanes. Vanes are available in many sizes and colors, are perfectly matched; and are easily glued onto wood, aluminum, or carbon-fiber shafts using a fletching tool called a fletcher or fletching jig.
Feather Fletching: This fletching is made from the wing pointer feathers of a turkey. The pointer feathers have a natural curvature distinct to the right and left wings of the turkey. A feather-fletched arrow will use either all right-wing or all left-wing feathers, never a mixture. You may use all left-wing or all right-wing feathers on your arrows, no matter which one of your eyes is dominant.

 

Flu-flu

 

This is the most common fletching arrangement used for target shooting, Three fletches are glued symmetrically onto the shaft 120 degrees apart. Some archers prefer four fletches per arrow attached 90 degrees apart.

So now you want to buy your own Arrows and get custom veins how do you do this? The Question I have for you is WHAT ARROW REST ARE YOU USING? because that’s going to determine your Fletching angle –

Drop away arrow rest = Use the Helical or offset Fletchings or Straight Fletching

Whisker biscuit arrow rest your going to have to use the Straight Fletching because the helical will pull to one side because of the Drag from the basket.

Good thing you asked it’s simple – look at this chart – find your number from lbs on the left side of it – then go across the draw length and then that is your suggested Spine – I SAY SUGGESTED BECAUSE IT’S UP TO YOU ..the spine could be on the line such as 60 lbs draw weight for a 28 in length is on the boarder of 350, and 400.

WHAT DOES THAT MEAN!!?!

Well here is how I look at it. a 350 spine carnivore is 7.5 grains per inch – and will FOC out at 10 percent with 10 grain insert at the tip 28 in draw and weight will meet WA spec for 60 lbs. and about 70 – 80 ft-lbs kinetic energy depending on your bow now look below

Results: Your approx. kinetic energy is: 72.84 ft-lbs.

Arrow Wrap/Cresting Weight (grains)
Additional Point Weight (grains)
Results: Your approx. arrow weight is: 362.0 grains.
FOC
Results: Your arrow FOC is: 10.01%.

 

NOW here is a 400 spine Carnivore built same way – note it won’t make min final arrow weight for Washington state regs @ 60 lbs draw weight BUT it’s lighter – the arrow will travel faster. we can change out the Arrow POINT to 125 grain instead of 100 grain this is what it would look like below this chart

Results: Your approx. kinetic energy is: 68.82 ft-lbs.

Here is with a 125 Grain field point or broad head with the same setup it’ actually fly s better then the 350 will and has very good kinetic energy – read below chart now

Results: Your approx. kinetic energy is: 73.85 ft-lbs.

Results: Your arrow FOC is: 13.14%.

 

 

The point of all this is to make you Educated to make your own decisions – if it was me buying new arrows I would get the 350 grains because they will be able to be used all the way up to 70 lbs!!!!!!!!!!!!! and at 70 lbs they will WRECKING BALL ANYTHING so if you want an arrow that will GROW with you – pick the 350 if your going to stay at 60lbs or below go with the 400s – it’s up to you but your options are open for ANY spine not just these ones I used as examples.

ok pin bushings or nock bushings what ‘s the difference – here you go pictures to illustrate what they go with and how they work – both products on the left side will insert into the back of the arrow – the bushings will act as added weight to balance the arrow in flight AND also save your arrows from being robin hooded.  I prefer the Pin bushings and pin nocks because I like to Rotate my nocks when Tuning broad heads.

Go to black eagle arrows website http://www.blackeaglearrows.com/

browse what arrows you want – they all come with Aluminum inserts and nocks –  you have to add compoinits like pin bushings, pin nocks OR nock bushing and F-nocks – you need to use the calulator and build your arrow on paper first then order them this will make sure you get the perfect fit and with custom veins you will even look good shooting !
