Which arrow tip is better? (bowhunters only)?

Question

I'm doing a science project and i need to know, which arrow has the biggest affect on an arrow's penetrating depth, a 75 grain, 90 grain, or a 100 grain broadhead tip?

Answer 1

I dont know either ,however I use 125 grain killer heads,and 55 to 70 lb. Speed Flight Cougar Bow and I wouldnt want to be on the receiver end.Friends say arrow can easily pass through one Caribou and kill another. Enough bull here though ,I would bet on the the 100 grain in Ur case.Would You post Ur or accepted answer here for us?Tanks

Answer 2

If you are doing a science project then you should already know the answer. I assume that you are using a controlled environment and not changing variables. There are many variables that affect the penetration, cut on contact broadheads for instance will penetrate more that expandable heads. So assuming you are conducting an apples to apples test you are using the same bow with the same type of heads (just different weights) and the same arrows. The lighter broadhead will fly faster but it does not carry as much inertia as the heavier one. The heavier broadhead will fly slower but have more inertia. The end result should be that the penetration is the same for all of the weights as the weight directly affects the speed and hence the inertia. If you were to adjust the bow so that each arrow is traveling at the same speed (meaning more kinetic energy would be transferred to the heavier arrow) then the heavier broadhead would have the most inertia and would penetrate deeper even though it is traveling at the same speed as the lighter arrow.

As "myhands" mentioned, it has more to do with the speed of the arrow and, of course, the mass delivered to the flesh at that speed that determined penetration.

The "grains" are a measure of weight. The speed of the arrow is determined by the poudage delivered by the bow. The higher grain delivers more momentum to the flesh, but, on the other hand, there is that much more inertia for the bow to ovecome at the moment the string is released.

In any case, the difference in the weight of the tips is so minimal, in comparison to the weight of the entire arrow. it probably makes little difference at the point of penetration. The grain weight may be more significan if the size of the prey varies. For a big buck, the tip's weight difference will not be significant. For smaller game, perhaps it does. It may make a difference if the hunter wants to destroy the game, or just bring it down.

For smaller game, bowhuntes use an arrow with specially designed fletching that actually slows down the arrow. The hunter fires from a shorter range, and less flesh is torn up.

Answer 4

I believe penetration depth is going to have much more to do with arrow speed than weight. An arrow shot at a higher poundage, will go faster/deeper. It depends a great deal on the settings of the bow you are using. I don't think this question can be answered exactly the way it is written.

Answer 5

Well that depends on the bow, wether or not its a over draw or its poundage settings. And the arrow shafts diameter and weight.
Not to mention the type of cutting head the broadhead is.
I shoot a 125 muzzy and its good. running about 75 pounds on the bow. No overdraw.

Answer 6

Scientifically speaking, the lighter tip should give you better penetration. The lighter tip should give a faster flight speed. Using the formula: E = M X V(squared). So you can see that the weight has a direct relationship to energy, and velocity has a squared relationship to energy. In plain english, doubling the weight at the same speed, will double the energy. Doubling the speed at the same weight will quadruple the energy. Hope this helps!

Answer 7

Actually, I don't know. I would guess that arrow speed has something to do with penetration along with grain. But I do know this: keep 'em sharp, sharp!

Answer 8

it's not fair to disciminate against non-bowhunters.
