Is there a rule on how much your arrow should weigh?
Just wondering because I was shooting a gold tip 5575 at 26.5 inches (shaft length) and with a 100 gn. point they weighed like 370 gns.
I got ahold of some Carbon Injexion 330s and decided to cut them at 29 inches just to keep them in the correct spine range, It wasnt until after I glued the insert in that I realized these arrows would come in right at 450 gns. once fully assembeled.
So my question is, is that way too heavy?
Should I cut an inch off the back? I believe a 28″ shaft is borderline between the 330 and 400 shaft.
I am shooting a pse x-force at 70 pounds with a 29 inch draw length.
I just got the oppertunity to try out the 330s for next to nothing, that is why I didnt just get the 400s and cut them to my original arrow length.
Also wondering what is up with the “Factory Cresting” is there anything special about this, or is it a fancy way of saying “we wrapped them for you”?
Does it matter which end of the shaft you cut off?
Thanks, I hope I am making sense.

There really isnt a rule in my opinion. Confidence in what you shoot is very important. Some guys like the speed and some guys like a heavy arrow. I usuually shoot an arrow between 420 and 440 grains finished. I still get some decent speeds and enough thump to keep my confidence up that my arrow will push through the animal. I focus more on my kenetic energy and what it does down range more than speed so i gi with a little heavier arrow. I personally dont get over concerned with speed. I just try to stay above 285 to keep my trajectory somewhat flatter. Keep in mind these are just my preferences. So if you shoot your 330′s and like how they fly and you are confident in what they are doing i wouldnt hesitate to shoot them. They will lob more than your previous arrows obviously but do some down range comparisons on penetration into your target. Hope this helps….good luck

I’ve found 400 grains to be about ideal. Enough weight for decent kenetic energy and momentum while still fast enough for flat trajectory.

Hey Stoney,

I might be missing something here on Spine… Not sure if I understand the reason to have a correct spine. I always assumed having a shorter stiffer arrow is a good thing. I also shoot a 29.5 inch draw 70lb bow and have cut easton axxis 340 to about 26-27 shaft length as short as possible to my rest and still have enough clearance.

I have always thought they shoot real good and will be trying the new Injexion 330 this next season. Please give me some info feedback on correct spine, like I said I just assumed shorter would give you a stiffer spine and thought that was good, what am I missing.

Also would think you could cut a couple inches of the fronts of your arrows you would clear the insert but would have to buy some extras. Let me know how the 330 are treating you.

To be perfectly honest I dont completely understand it either, but from what I understand you do need some flex in your arrow to get it to fly right.
I know that there is such a thing as too stiff of an arrow, I know that when all of my correct data is entered in on the archers advantage program it tells me I have “optimum spine” by changing shaft length from 29″ to 28″ it tells me “slightly stiff” and changing it to 27″ it tells me “too stiff”. but by changing my draw weight from 68 to 70 brings my 27″ shaft back down to “slightly stiff”.
I also remember dixon saying in one of the podcasts that his arrows were a little bit overspined causing them to tune toward the riser.
However I may not know what I am talking about so hopefully someone with a better understanding can shed some light on this for us
