thanks alot,no bleeder blades any way.back years ago bleeder blades would break.I never found a bleeder blade when i did kill a deer.I would the barely file the point into a diamond shape about 1/32" to keep it from sticking in a rib. those single bevel broad heads look good to but I do not have the money to spend.I am going to make some broad heads out of 1/16" steel with single bevel bet it works.

I agree with the others; you should have no issues with either bow being effective.
In a nutshell, Joe... FOC is the distance in fractions of an inch forward of the center line of the arrow at which it balances. Example: a 30" arrow's center would be 15". If you mark 15" and balance the arrow on that mark and it balances, your FOC is zero. If you move the balance point forward two inches and it balances there, your FOC is 2". The heavier the front end of the arrow, the further forward the balance point moves. As with darts (the throwing kind), best flight and accuracy is obtained by having more weight forward of center, leaving the feathers to due the guiding. The higher the % FOC, the easier it is for the feathers to correct errant flight (up to a point).
To determine %FOC, use the formula (BPL-OAL/2) / OAL=FOC
BPL=Balance Point Length (measured from nock groove to balance point of complete shaft)
OAL=Overall arrow length measured from nock groove to back of head or point (BOP)

Example: A 28" arrow with a balance point 18" from the nock groove will have a FOC of 25%

(BPL-OAL/2) / OAL+FOC
(18"-28"/2) /28" = FOC
(18-14") /28"= FOC
FOC=4"/28"=14% (approximately)

Here is some more info for you to play with. If you make your own broadheads, they may come out a bit light. if you don't use a heavy insert, and use a standard one, you will have to reduce your spine. With field points you start out around .756 spine for 40 b. You might want to increase spine for a broadhead (although they worked for me with 125gr broadheads and standard inserts) if you add heavy inserts. In that case a 1916 is a tough arrow at .623



How to pick the right aluminum arrow without charts!

Here's the deal: There are only nine arrow spines you need to start off with bows from about 18# to about 100#. (Note that this is an approximation and you’ll see why in a second).

IN GENERAL for 28" ARROWS +/- 1" (27 - 29") and 100 - 125gr heads:

18# - 23# 1516
24# - 27# 1616
28# - 33# 1716
34# - 42# 1816
43# - 52# 1916
53# - 60# 2016
61# - 70# 2117
71# - 80# 2216
81# - 100# 2219+ (Might want to play with 23xx, 24xx and larger shafts as it can get a little dicey at those weights, since bow efficiency starts diminishing after a certain weight.)

If you go to a 30" arrow, jump up one spine number, if you go to a a 32" arrow, then go up two spine numbers. Ditto for going shorter, 26" one spine down, 24" two spines down.

Head weight will also affect spine, however, it will require 45-50 grains to jump one spine number. For example, if you're shooting a 40# bow and using a 29" 1816 with a 100 gr head, going to a 150 grain head may require you to jump to a 1916.

This WILL NOT give you the perfect aluminum arrow for a given bow. It will give you a tunable arrow, and that's all you need for starters. Once the arrow is tuned, you'll know if you're compensating for a stiff or soft arrow by the tuning requirements. Then you can fine tune arrow choices by juggling wall thicknesses and diameters.

For example, if you have a #41 @ 28" bow and are using a 29" arrow, you'd pick an 1816, right? And that would work. If you find that you have to move the rest/strike plate out a little more than you’d like, then your NEXT set of arrows might be 1914s. They are the same weight as the 1816s, but a little stiffer.

Regarding Fastflight Fight (low mass/low stretch) strings. The difference between Dacron and FF is on the order of 5#, in a worst case scenario, so if the right arrow was chosen in the first place, it should still be within tunable parameters.

In addition, if I know a particular bow, I might suggest an arrow that's not one of the primary spine numbers. A certain #57 bow might work very well with a 2114, for example.

*Aluminum arrow nomenclature: the first two numbers denotes the shaft diameter in 1/64" and the second two are the wall thickness in 1/1000". For example, a 2016 has a 20/64" (or 5/16") diameter and a wall thickness of 16/1000". For those of you who would like more detailed information, below is a table complied from Easton's aluminum arrow charts, showing the name, spine, weight and grains per inch for each arrow size.

To convert the spine (deflection in inches) to approximate draw weight, divide 28 by the deflection.

For example, an 1816 has a deflection of 0.756",
therefore: 28/0.756 = ~37#, the midpoint of an 1816's acceptable weight range.

Note that Easton does change their offerings from time to time, and therefore some entries may no longer be available and some new additions may not be listed.
Shaft Spine Size (inches) Weight (grains) Weight (gr/in)
1214 2.501 142 - 24" 5.92
1413 2.036 153 - 26" 5.88
1416 1.684 194 - 27" 7.19
1512 1.554 157 - 27" 5.81

The 2007 Easton catalog introduced a new version of their Gamegetter XX75 shafts. Now sporting a black anodized finish, the shafts are available in four sizes, based on their carbon arrow nomenclature. In 2009, the XX78 Superslam (digital) shafts were given a shaft diameter nomenclature as well.

Essentially, a 500 series shaft is identical to a 2016, 400 = 2117, 340 = 2315, and 300 = 2317.

This thread has a wealth of good solid information on it, it is one of those that needs to stay around.
With my 40# bow I shoot the 3D ranges with a 29” 600 spine arrow and 175-200gr point. My hunting arrows are 30”, 500 spine, 250gr points, and 50gr inserts. But nothing is in stone for me, I’m continually trying something new! Thanks for the foc explanation Kirk, slipped my weak mind. :roll:

Good detailed info on aluminum shafts Grizzly, thanks for sharing, again; this thread should be sticky.

thanks alot for this information.I ask an you all delivered.I wonder if ish,fred bear.howard hill knew this information.the common sense things such as keep your broad heads sharp was second nature to them.can you build a perfect arrow probably not. we should try our best to make humane kills.know your limitations an stay with them.we as tradhunters have the responsibility to teach,mentor an be a good example.I really feel proud to be a menber of your gang.
