I read an article a while back about shorter bows tend to shoot faster .
I had my doubts about that until now . My new 58" 50# Super Grizzly seems to fire an arrow faster than my 60" 60# Bear Takedown .
Have any of you ever noticed the same thing ?
What GPP are the arrows for each?
i have recently compared my static tipped RER Retro (53#@28", 58" length) with my new static tipped RER LXR (52#@28", 64" length), and that seems to be the perception for me. shooting the exact same arrow, the Retro seems to be a bit "snappier", although i think most of that is simply perception on my part, due to the smoother draw of the longer bow.
i plan to chrono them at some point and see just how much difference in speed there really is. really interested to see how it shakes out.
Even shooting the same arrow .
That Super Grizzly just has more pop . I have noticed that the S Griz has a more radical recurve . Might be part of it .
Shorter limbs recover faster is one reason, though its not always a rule on short bows as many have more deflex in the riser/ more forward handle to allow longer draw so as not to hit the bows stack point..once you get into stack area you will lose energy, and this will cost some speed.
I have a 2 vintage Victor Super Grizzly's. One is a 45# and the other is 50#. They can really launch an arrow.
It's possible that the shorter limbs are more ideal for your draw length; you might be getting more out of them because you are not working the longer limb fully at your draw. It seems there is always some form of compromise involved; you can opt for max performance, or a smoother draw, better string angle.
All bows are not created equally.
Your statement is like saying, "I read an article that short cars go faster than long ones."
There are so many variable factors in how the limbs are built, and the geometry of the design that come into play that makes it impossible to generalize Short bows or longer bows.
Graps if the gpp on each setup is the same I actually don't doubt your findings one bit. Kirk, being as they are two Bear bows with very similar limb construction its actually a good comparison he's making in this case...if it were a 58" bamboo bow of one make vs a 60" carbon/foam bow of another make the whole situation would be more gray as you point out.
Grape if you compare the two Bears the Super Grizz has a straighter riser with less distance between the deepest part of the grip and the limb fades and a marginally lower brace height VS the Takedown which has a little more deflex in the riser...whether your draw is 28 or even 29 you are likely working the Super Grizz limbs more and probably hitting the peak efficiency on that bow. The stack point on the last Super Grizz I tried was somewhere just a hair past 29" if I remember. The 60" takedown you have is probably good to 30". So this would make sense if gpp is same on each and you're shooting both with a consistent release...there's always the additional possibility that you're getting a cleaner release with the lower poundage bow which also helps speed.
