My children bought me a new compound bow for Father's day, it's my first bow. There's more to hunting with it than I first thought. I've got some 500 spine arrows that shoot fantastic with my field points and my hundred grain fixed 3 blade broadheads I'm only shooting about 55 lb not really sure I need to get anything else , only shooting out to 30 yards confidently right now
Thank you Outdoor Man! I am a recurve/ Longbow shooter and I’m very talented at getting things wrong and being frustrated!!! One day I found out that I don’t actually know anything whatsoever about archery 🏹 other than I am not good at it yet I enjoy it!!!
Ive been in archery for 45 years. One thing I have found is that there is a ton of misinformation out there about archery in general because so many folks misinterpret what they hear or read, then pass that along to someone else who has to figure that out and it just gets worse. Sticking to basics will always get you steered in the right direction. When guys try to get everything "maxed out" (speed etc) is when it gets confusing and stressful. Good luck to you.
This is a good video. One thing I never hear anyone talk about is the lever arm and moment around an axis. I am a collision reconstructionist and I deal in physics all day long. Force, lever arm and moment calculations in my business equates to damage among other things. In archery it would equate to flex in the arrow shaft. Say you have 2- 50 pound recurves. One has limbs 3 inches longer than the other. The longer limbs will return slower, having more mass, giving that bow a lower fps shot. The inertia everyone loves to talk about would be different on those 2 50 pound bows. That would mean different spine requirements. So it is not just poundage, but speed of return that affects spine. Your point regarding why and how a fixed broadhead can steer the arrow is an excellent point.
Interesting point about length of lever arm together with poundage effecting the bowstring's speed of return, and speed of return effecting upon flex of arrow shaft.
Great info. Im getting back into archery after 15 years. Went and got a V3. Man there is alot to it. And i thought there was alot to know shooting rifles, big learning curve 👍
Too much flex for the broadhead. Thank you. You answered something the local dealer absolutely refused to even help me With just to sell some arrows they had in stock over ordering what I wanted
good info man, stuff we already know but you put it out there in a way that you dont have to think about it much really simple with your way of wording!
thanks...brushing up on archery stopped 2 yrs ago...house fire/bow gone. I always went a little heavier myself. looking to start daughter with Real bow....like 45-50 lbs /28 draw....and looked up spines...planning on 400.
New to archery, just purchased a bow. Liked your information..👍 Could someone just purchase the 250 spine Arrows, cut to their length and call it a day?
I brought an 70lb compound bow and came with 550 spine and 30in arrows in lenght . Is it dangerous to shoot? What can happens? The arrow may break in release? It is a serious question. Thank you.
What do you recommended my DL is 28” and 70Lbs DW I’m getting the Easton axis 5mm 300 spine is that a good arrow spine thanks for hunting whitetail and hogs
Thx for the info. I’m currently shooting a bear motive 6 at 46lb I’m currently working up to a max of 50lbs that my limbs will allow. Are my Easton power flights with a 400 spine ok for that setup?
Draw Length 26" 65lbs what size arrows would i need? Carbon? And Draw Length 26" 70lbs what size arrows would i need? Thank You Much! I shoot 100 grain tips if that matters
Hi your photo at 2:53 when your showing the bow at full draw its reading 50.73 pounds . How is that possible if you have any let off at all with the cams ? wouldn't the reading at full draw be less some where around the 20 lb weight ? So wouldn't you want to watch the scale and as your pulling the bow back before you get to the cam's let off . So in your photo the 50 .73 reading would have been at the 25 inch range and not at full draw length ?
Stiffer isn't always better, especially if you are shooting traditional archery. The arrows do need to very slightly bend around the shelf/side plate as they travel off the riser. If an arrow is too stiff and can't bend, then the riser will slightly push the shaft off to one side.
In case of doubt should I go with a lower or higher spine? I've been using easton inspire 570 with my 36 -38 lbs bow, but i've been searchin for lower cost options, found one that looks good but the spine is either 500 or 600, should I get the 500 spine or 600?
guy at archery shop picked out 350black eagle outlaws for my 60 pound 27 inch arrow with a 125 grain broadhead up front should i have gone to a 300 spine or will that work?
You can use a 500 spine with those specs, but I would recommend a 400 spine. Speaking in terms of impact flex, you'll see better penetration with a stiffer arrow.
All the charts go by draw weight.... wouldn't there be a big difference between a 70 lb bow with IBO of 350 and a 70 lb bow with IBO of 280 when selecting spine?
Yes it can make a difference. I truly believe most arrow charts in use today were the same ones used 20 years ago. Companies need to adapt to changes by the bow manufacturers.
The most confusing, non-intuitive number for novices is arrow spine. The best way to think about it is arrow deflection (bending) for a given arrow length and force, rather than incorrectly thinking it's "spine weight". Thus a higher poundage bow should be matched with a stiffer, LOWER deflection arrow. Such as 500 for 40-50 lb target bows, 400 for 50-60 lb compounds and 340 for 60-70 lb compounds. It also depends on draw length as it relates to arrow length, type of release, and field point weight (thus the need for look up tables).
Some beginners like to choose a 600 spine, even if their draw length is short. For example, 600 spine, 27" DL, and 30lb are way too stiff; they did not notice that arrow length is part of draw length.
If you are using a standard aluminum insert (about 12 grains) and your actual arrow length is less than 28" you'll be ok with the 400 spine. If your arrow is longer than 28" the spine will be weaker, thus creating impact flex when your arrow impacts the target. This results in a loss of penetration. I generally recommend a 350 spine for your specs. Shoot straight! 🎯
He said "Element are working on reducing the flex of the arrow". This guy doesn't know what he's talking about spine, and if Element are doing that they don't know anything about arrows.
Hey bro, what weight have you got up front? Want to try the 100 grain inserts but it's close to being under spined, wondering if I'd have kick out problems
Kevin Emard it’s a totally reckless idea and the injuries one could suffer trying it are almost countless. Just to know draw weight? I’m not sharing any ideas because purchasing the proper device is the only logical solution to his problem.
i shoot victory gamers 350 my draw is 28.5 and my bow is 70.1 with my 125 gr broadheads they wont fly st8 unless i bring my bow down to 66 lbs and i also want to add 30 more grains for the front seems as tho my spine is to weak i tried 250s and it was alot better but diffrent company arrowsx
Intersting heres me buying $1 arrows off aliexpress 😂 they deff don’t shoot the best but atleast when i miss something i don’t have to look for the arrow
I'm shooting a Mathews Vertix with a 29"draw and a 28" axis 400 that seems under spined at 62lbs when I add manufacturer's IBO rated speed that Eastons chart goes by hard cam but others charts say 340 spine does that seem more correct
In my opinion I think a 340 spine would be a better option for you. That Vertix has an efficient cam system. I think as we progress with new bow technology many of the spine charts have not been adjusted to reflect the kinetic energy generated by newer bows which results in more flex in your arrow.
tried checking your data on the Easton Charts. Vertix is rated 343 fps. 341-350 fps. you add 5 lbs to your draw weight when checking the charts. so 62lbs +5 lbs = 67 lbs. YOu will be under the 67-72 lbs with 28" arrow. Definitely 340 spine
@@archeryology101 so I have a cheap bow and some cheap arrows and my draw length is 29 inches and my arrows are 28 3/4. I upgraded and got a new bow ibo 330 and plan on going to the bow shop this week but I'm seeing good deals on eBay for arrows so I kind of would rather get my arrows off eBay instead of the shop ,but idk if my arrow length will be the same on this new bow. My draw length is 29 inches 60 lbs draw weight and I'm gonna shoot 125 grain Broadheads with a 23 grain insert. On the chart for the Easton 6.5 it says 60 lbs with a 28 inch arrow should shoot a 400 spine but 29 inches should shoot a 340. So I'm not sure what spine to go with bcs idk how long my arrows will end up actually being. I'd rather shoot the 340 because it's heavier

Great info thanks. As a starter, what is a simple weigh to use on a say 70 pound bow with a "standard" brawd head.? For hunting.
400, then go from there
Now if poundage and arrow length under or at beginning edge. You add more weight in tip / broadhead.

My scale locks in at the highest weight, which was at the peak of the draw curve.
I am a beginner. If stiffer is better, why not just always get the mot stiff arrow?
Exactly 👍.

@@archeryology101 so if the spine is 500 that means the arrow is stiffer or is it the other way around. lower number spine equals harder arrow spine?
Lower number means stiffer spine, except when talking about carbon express, they are the opposite.
@@archeryology101 thank you im new to archery im glad i saw your video they are very helpful subscribed!!!!
I need strong arrows, wich spine I need?
i like the old system like a 2218 or 2016 it more custom for your setup
I have 80lb bow with axis 260's (516)grain with fps(287). I would like to be around 315fps I'm wondering what arrow I could run for that speed?
Element Storm 250 spine would get you in that ball park. It's a bit lighter than your axis and increase your speed.
