Arrow Penetration

[Steve71]

Would you agree that a 520 gr arrow shot from a 43# bow traveling 170fps would have the same penetration as the same arrow being shot from a 55#bow traveling 170fps?

[Don Stokes]

Yes, if the arrow is flying perfectly in both cases. The arrow doesn't know...

[Over&Under]

I believe it would, but I don't see how that is possible if the arrow is the same weight.  Wouldn't the 55# bow shoot the arrow faster, no matter what??

[Charlie Lamb]

Over&under... while Steve's example may (or may not) be a slight exageration, it is very possible for a lighter bow to out perform a heavier one. They'd probably be two different designs, though.

[drewsbow]

no , depending on design a very poor bow at 55 may not shoot any faster than a well made 43 :0)

I agree with you, except that 12#'s seems like alot of difference to make up in design.

 Although you guys would probably know, you just started in this thing called traditional archery

Total arrow weight being the same really isn't the only factor. If one arrow had a 100 grains more head weight or more I'd go with the one with the heavier head to out penetrate the lighter nosed one even though both arrow setups weighed the same & both flew at 170. Of course different arrows would be needed to assure good arrow flight. But both would still weigh 520 grains.

  Same arrow is able to be used for both, then 170 is 170.

Same arrow same point weight going 170 fps same BH. same penatration. If you can throw it 170 fps, its the same.....

[overbo]

What's the point of the question?

[Steve71]

Everyone is worried about poundage of their bow but that is not the only consideration.

[WidowEater]

Bow efficiency is something that gets hashed out here quite bit.  It is on the rise among manufacturers especially with carbon backing and new and better methods of construction.

[Don Stokes]

Last season I shot my Torges longbow drawing 57# at 27". Next season I'll likely be shooting a Quillian Patriot recurve, 40# at 28", due to old shoulder problems that have come back. Another alternative is a Quillian r/d longbow, 50# at 28". These bows all bare-shaft at same arrow spine, so I can shoot the same shafts from all three. Speed appears to be about the same, too. The animals won't know which bow I used. Neither will the arrows.

[KentuckyTJ]

I think Don hit on the answer. The key to your question is if the two arrows of the same specs are flying at the same efficiency. It would be difficult to get both arrows from two different bows to fly with the exact same paradox so depending on which arrow hit the target straighter would be the deciding factor of which penetrated more.

[Hattrick]

What Bob said,it boils down to bow design i have mid 50pd bows that out shoot D shape bows in mid 60pd range. If all`s equal going 170'per sec its the same. Some bows get there some don`t

[TNstickn]

Absolutely

[deadpool]

one thing u forgot to add in the equation is the draw length, no?

[James Wrenn]

The same arrow leaving a bow tuned right and it is all the same.The arrow does not know if it is leaving a 70lb bow or a 40lb bow.:)I quit worrying about the weight marked on a bows limb a long time ago.The speed it shoots the arrow is all that matters.That still does not mean you might not get some flack for shooting girly weight bows at times even if they might be out performing the guys bows doing the talking.  :D

Monty Browning once said his 1500gn arrow used to kill his big bear was measued at 110fps.I think it was a 90lb bow.Now you tell someone that you are going to go shoot such an animal with a 50lb Quinn or Das bow and you will hear grief even if they both will match and pass that performance with the same arrow.Sometimes we get too caught up in numbers for our own good.
