5 Ways to Get More Speed From Your Bow!
Comments are disabled for this video.
I'm going to show you the conventional and unconventional ways to get more speed
from your compound bow My hunting bow of choice is the white carbon RX9 Ultra
This bow is set at 28 and a half inches for today's test The bow is set at 65 pounds
My let-off is set at 85 percent I'm using a Hamski Pro Hunter Pro rest
I have carbon smackdown stabilizers and the white sl bar and I'm using an eastern full metal
jacketed arrow that weighs about 550 grains We're going to shoot that through a chronograph and the
I'm going to take you through the process of how you can increase your speed from your bow
without compromising accuracy and performance With the current setup of the bow this bow should
be around about 28 and a half inches but before we start the test I do want to confirm the
What is the draw length of this bow and what does it actually measure I did reduce the poundage
Took the limbs out two and a half turns This would increase my draw length so I just want to
double check it and make sure before we start that we can compare apples with apples So whe
I draw this bow to confirm the draw length using the draw length arrow 27 inches
It is roughly in the throat of the grip and then you have to add one and three quarters
So this bow is currently set at 28 and three quarters so it is slightly longer in draw length
an what I thought 28 and three quarters is fine The draw length that I am comfortable with is 28 and three quarters
The draw length for my target bow is 28 and a half inches because it's a long axle-to-axle bow
and I found that I get the most accuracy and consistency from that My hunting bows I prefer
29 inches because I do get a little bit more speed but with this being a little bit shor
It's ideal for the test I want to conduct today and what I want to show you It's also important
For me to look at the weight of the bow so that we know what that is set at If you are using a bow
I'll scale any bow scale for that fact remember to put an arrow in should the
Lube break or if something happens that you don't dry fire your bow So this bow is currently set a
Just under 65 pounds 64.82 and this is a good base for us to start from The arrow that I am using is
A eastern full metal jacket This arrow I'm going to weigh this arrow just to make sure we know
e weight of this specific arrow which tells us where to start This arrow weighs in a
545 to 546 grains So to basically recap 546 is just under 550 grain arrow 28 and three quarter inch
bow set at 65 pounds We are going to shoot this over a chronograph to get a reading and then we're
I'm going to start making some changes to see how you can increase the speed of your bow Got the
Garmin Xero chronograph is such a nice small unit and you can do anything with it you can use
Your rifle your bow your air rifle it's such a nice little gadget to have I'm just going
To make sure that I've got this set up right for my bow We'ready to do shot number one that's 245.5
That's the first shot so it's not very fast for a hunting bow it's a quite heavy arrow
That I'm shooting and my drawing isn't that long Let's start with the three easy ways on how
You can increase the speed from your bow there are some nice extra tips I'll give you at the
End of the video so make sure you stay tuned for that part But let's start with the easy
stuff I'm going to increase my drawing by three quarters of an inch to see what the speed is
The difference is going to be We will measure the weight to see if there are any weight variations
that come from us just adjusting the drawing so let's do that step by step and see what the weight is
The speed difference is going to be significant With this HPX cam it's so easy to just adjust your draw length
This module that I have on this specific bow gives me three quarters of an inch of adjustability
If I want to go a little bit longer in draw length I do need to change the module itself
But this specific module that's in here right now is going to give me three quarters of an inch
longer draw length but what is important to know is that you do not want to give up any accuracy
Make sure you are comfortable with that extra little bit of length and that you do not give up
any consistency so it's easy to play with maybe half an inch of draw length on your hunting bow
Accuracy is the most important thing with anything with archery it's obviously accuracy and draw length
It's such an important thing let's just see out of curiosity what the difference in draw length is
I'm going to do it I've increased the draw length on this specific cam by three quarters of an inch
I've taken it from the small F to the big E so it should give me three quarters of an inch longer
and with this I'm just going to measure remember it was 27 inches on the R itself so just to
Compare it it should give a reading of about 27 and three quarters and I'm also jus
I'm going to use the poundage scale to check if there's any increase in poundage there should be a little
A bit of an increase it already feels a little bit longer on the throat of the grip is 27 and
Three quarters this is giving me a reading of 29 and a half inches so this bow is set at 29
and a half inches I also want to see what the weight has done so the weight is about the
Same 65.36 so not really any gain in weight but there is a gain in draw length three quarters of
An inch let's shoot this over the chronograph and see how much speed you will gain if you
increase your draw length by three quarters of an inch using the same arrow it's only the draw
That's a different shot number two 253.3 feet per second three quarters of an inch will give
You gain eight feet per second and that's about the industry norm for every one inch you
Increase your draw length or decrease your draw length it'll give around a 10 feet per second
difference With draw length comes a price and you need to make sure that you are happy to
Increasing the draw length can cause a form issue to come into play and
your shots will deteriorate more the more you shoot throughout the day
You might notice some inconsistencies so make sure that if you are going to increase your
draw length you are staying true to good posture good form good accuracy and good consistency
If you are going to shorten your draw length you're going to lose some speed and
that will cause other issues with aiming being a little bit more erratic and obviously
You'll lose some speed and there will be some fit issues that will also come into play so make
sure you know what draw length you want to shoot or what the maximum draw length you can is
Shoot accurately and consistently We know the poundage is set at 65 pounds What I am going to
do before I actually draw is I'm going to increase the tension by one full turn and I'm going to
Make sure what I do at the top I do at the bottom very important otherwise your tiller is
going to be out and you're going to not be as consistent It is important that you know that
Your limb bolts are always tightened the same way so this is one full turn and I'm done
Curious to see how much the weight has increased from 65 pounds I'll make sure to draw
This more than once to make sure we have a consistent reading so this is now 69.58
Pounds so there is an increase of almost five pounds with one full turn out of the bow itself
Let's just double check 69.40 so there's consistency so it's about a four
A pound increase in poundage let's shoot it through the chronograph with the exact same arrow and
see how much gain we will get from just over four pounds This is going to be shot number three
This is shot three all in flow and sequence 259.3 feet per second so screwing my bow in one full turn
Turn gave me four pounds more on draw weight and it only gave me five feet per second more
on the chronograph is that higher poundage worth pulling for that extra few feet per second
Something you have to keep in mind is not over-bowing yourself getting to full
draw obviously also causing you to go out of posture your left shoulder coming up
You're tiring quickly your aim isn't that steady and then the execution isn't that smooth To
recap with a three-quarter longer draw length and four pounds more we've gained almost 15 feet
Per second is that 15 feet per second worth the increase in draw length and worth the increase
in poundage Will that affect your posture and your shooting technique Make sure that you
Are you comfortable with these changes the easiest next step to increase your speed is simply
to switch to a lighter arrow which we'll do now but if you're going hunting make sure the arrow
It is still heavy enough and with the weight of the arrow speed also brings penetration and
kinetic energy is measured in that way so make sure you don't have an arrow that is too light
Speed does not always equal penetration This arrow is 457 grains so this is almost 100 grains lighter
an the full metal jacket that we use this is a eastern 6.5 arrow it's got a 50 grain brass
e front and it does have a 100 grain point in the front like I said almost 100 grains lighter
This will be shot number four let's see how much gain you'll get with a slightly lighter arrow
283 feet per second 283 feet per second with an arrow weighing over 450 grains we started with a
An arrow weighing 550 grains you need to make sure what kind of speed you want to shoot
of animals you want to go and shoot but this was the third thing that we changed and we have
Increased our speed by almost 40 feet per second one of the small changes you can make to your bow
This bow is set at 85 percent let off but will it be worth it I'm going to take this
Down to 75 I prefer shooting these bows at 75 let off because I'm shooting my target bow at 65
I'm not doing it for speed I'm doing it more for consistency and accuracy because I do prefer a
more solid wool and harder at the back but will that little bit of change in let off make a difference
The difference in speed we need to be technical about this if I'm going to change my let off here
From 85 to 75 it's going to change my draw length and with draw length there may be some speed changes
That's also going to come into play so keep your drawing in mind to ensure it remains
consistent throughout the process This is a quarter in shorter we are going to take the shot
and see what the speed is going to do but with the change in the let off itself with
the quarter inch shorter draw I am not expecting there's going to be a big difference
I'm actually expecting a slight decrease in speed but let's have a look by changing the let off
From 85 to 75 I saw the speed drop from 283 feet per second to just under 281 feet per second
Two and a half feet per second difference so for a hunting bow ideally if you are going to
be in situations where you are going to hold the bow a little bit longer in hunting situations
Going to a lower gear to see if you can get some more speed in my opinion will not necessarily
It would be more beneficial to receive an 80 or 85 percent reduction for those
people who don't really know what "let off" means if it's an 85 percent let off it means you're only
olding 15 percent of the actual draw weight that you are going to pull so if we say a lower
Let off of say 65 percent means you are holding 35 percent of the actual bow weight
You are pulling so make sure you know what your bow is set out and what your draw is and
do not compromise on draw length as it is probably one of the most important factors when
When it comes to accuracy with the changes we've made today the most significant change
we've seen so far was with the arrow weight where we've seen an increase in speed by jus
Changing arrow weight I'm not going to shoot my hunting bow longer in drawings to get extra speed
Maybe if I'm going to go and hunt dangerous game like Cape buffalo or thick-skinned animals and
so on I might increase my drawings to get that extra feet per second for that extra foot pound
Kinetic energy for that extra momentum but otherwise if I'm going to shoot longer distances
and under my normal hunting situations I will not compromise on drawing one of the
smaller changes you can make if you are sitting at home with maybe a slightly older bow is if
You've got a peep sight with the old tubing in it get rid of it get a proper true peep or jus
A peep that is a specialty archery peep or a hamsky peep that you put inside your string to get rid of
e extra rubber that takes a lot of extra speed out of your bow if you are using a
Whisker biscuit rest that friction that the arrow has on the rest itself will take a little bit
of speed away especially at the longer distances if you've got a rest a normal drop away res
You know any high quality rest that's on the market today that is something that I would
recommend you use you will get some extra speed from that and you will get good accuracy and
Consistency from it if you do have fat old cat whiskers inside the string itself that will also
decrease your speed if you are having difficulty with a lot of vibration on your bow and you wa
To make your bow less noisy I would recommend you go buy a new one but keep
Do you mind if you've got the cat whiskers and all those things on the string itself it does play
A factor in speed if you still want to increase speed use other string materials BCY has a good
variety of different string materials You can get someone to make some strings for you that's
The fewer strands you have on it the noisier your bow will be but you will get more speed but
remember speed does not equal accuracy If you shoot fast you're only going to miss fast Make sure
And I keep saying this make sure you've got the right drawing make sure your bow is tuned
If the cam timing is not right or your arrow is not correctly spined with your bow you
will not get optimal speed accuracy and consistency from your bow What are you doing
