Differences Between Broad Heads

Now that hunting season is again here not a single day goes without asking about broad heads. One of frequently asked questions is "Why my broad heads do not hit what my field points do?". I think there were simple reply to this question. Truth is, there are various things that can cause broad heads & field points to impact in a different way.

Differences between broad heads & field points
First, let us look at dynamics of 2 different points and 100 grain field point can average ¾-inches in length & 21/64-inches in an diameter. The 100 grain broad head, although the weight is same, average 1 ¾-inches in length & with blades, can encompass diameter of about 1 3/16-inches. All these blades will give you numerous planning surfaces to grab air. Why these points should hit same spot? All these differences as well cause broad heads to be critical to tuning flaws & flaws in an shooting form. In majority of the cases a can will their groups with broad heads to be larger than the groups shot with an field points. What is important is your broad heads fly well & are grouping. In case this is the point, however they are impacting couple of inches from the field points, then make a sight adjustment.

What if your broad heads are flying very wildly?
In case your broad heads are flying wildly & you are not able to hold the group, then there is problem in the following areas: tune of bow, shooting mechanics and arrow spine. In case this is an case, then taking bow to the experienced technician is very good place to begin. They can find something in tune of a bow or else in your form, which can correct all your problems fast. If everything seems to be in correct tune, paper tuning is good place to begin. This way of tuning will give you blueprint of how arrow is leaving bow & can show how to do it correctly. Again, well trained professional will make this procedure easier.

Broad head design
One main factor that will help you, is broad head design. There are many great broad heads on market. I favor heads, which are compact in design and broad head, which is shorter in an overall length & has shorter, lower shape blades is suitable to plane less & impact closer to the field points. My favorite is Sonic 100 by American Broad head Company. This broad head is just 3/4" in an overall length as well as has 7/8"-cutting diameter. Its flight features are tremendous, even at the speeds in excess of about 290 fps. It as well penetrates well and I have used with great success on an 400lb black bear, many whitetails as well as pronghorn antelope.

Mechanical broad heads
One more quick fix that lots of people are using is mechanical broad head. These heads will keep blades very closed in flight, thus, eliminating any planning surface. They will fly like your field points and drawback to mechanical broad heads is reduced penetration on your game. Quite a bit of arrow's kinetic energy is been expended in opening of a blades. In order to use an mechanical heads efficiently, your setup must generate 50 foot pounds of an kinetic energy.

Broad head alignment
One ignored part of broad head tuning is an alignment of broad head to arrow shaft. This comprise of assembling broad head to arrow shaft & spinning it to ensure that it runs true. In case there is any kind of wobbling in shaft broad head combination, it may not shoot constantly.

which archery arrow spine do i need?

I dont know what spine i need, i used 690 eastern redline grain spines when i shot my recurve at 27 pounds and now at 34 i want to buy new arrows so i have 2 questions
what arrow spine will i need?
and is there a way to figure it out so i will always know exactly what everyone needs?

When it comes to recurve fingers you can get somewhat close with spine charts, Easton actually has a web application to guess arrow spine. Go here

Depending on the arrow you want to buy, redline I think is considered a hunting shaft, you select hunting, target, or youth.
