Question by tony167n. Uploaded on July 01, 2009
What do you mean by fishtail? Can you see them oscillating in flight? Or are they suddenly flying off in odd directions?
I can see the back of the arrows wobble and they hit the target at a different spot every time.
Your fletching is hitting your rest upon release.
That sounds right buckhunter I'd try a new rest , I like the whisker bisket it let's your arrows fly true every time. If your going to change I'd do it soon.
When you retrieve your arrow are the fletchings still in tact. I had a similiar problem and I fixed it by installing a drop away rest. The whisker bisket was ripping the flectchings off the arrow just at the very front ( about 1/8")and it caused the arrows to wooble.
Are you using the same weight broadheads as your field points?
The broadheads are the same weight and the fletchings are fine but I looked at the broadheads on the arrows and the blades are not aligning with the fletchings, would that have anything to do with it?
Put a field point back on one of your arrows and shoot through paper at about 3 yards. Tell us what the direction of the tear is and the problem can probably be corrected. The hardest arrow flight problem to correct when shooting broadheads is too little spine in the arrow. I have tuned lots of bows and I never could see a difference whether the vanes and the blades line up or not. There are too many other variables. To check to see where the fletching is making contact,I've always used spray on foot powder.
Some people say that aligning the broadheads with the fletching is the way to go but I don't buy it. What if you're using 2-blade or 4-blade broadheads with 3 vanes?
I don't understand how just switching from field points to broadheads would cause fletching contact, unless the shafts are rotated 180 degrees. But, life is full of learning experiences. Should check with some talcum powder to verify before making any changes.
Otherwise, all I can think of is that the fletchings just aren't able to stabilize these broadheads, the bow is out of tune, or the arrow spine is incorrect. Might paper tune and try other broadheads, or different vanes. Beyond me at that point - I'd be going to a pro shop begging for help. Maybe someone else here knows more. Please let us know what you find out.
I'd like to add here that shooting through paper is the single most important thing that you can do to properly tune your bow to shoot broadheads. Once you have a perfect hole through paper with no horizontal or vertical tear at all ranges that you shoot, you are 99% of the way to perfect flight with a broadhead.
Mechanical or fixed?
libertyfirst is correct. Paper tuning is the single best method of tuning your bow.
I'm using muzzy 3 blade broadheads on size 400 beman MFX arrows with blazer fletchings, the bow is about 60 pounds, and i am using a whisker biscuit, my draw length is 29 inches
Release or Fingers?
How long are your arrows? Nock point to end of shaft, not including broadhead/insert. Did they come with the Blazers or did you put them on?
I had a similar issue with my arrows, but it didn't matter if there was a field tip or a broadhead on the end. I change to a stiffer arrow and the problem went away.
you could try diff broadheads
The reason I asked about arrow length - you can reference the Beman selection charts to make sure you have the right spine arrow.
Bohning recommends 2 to 3 degrees offset for the Blazer vanes. I was having fits with broadheads until I increased the offset from straight - actually just used a helical jig. Get a bit more noise but broadhead control is much better.
Definitely paper tune before doing anything else. My bow is pretty much on but some broadheads are still just not accurate. May have to try a few. 85-100gr are just fine for deer. Good luck.
frist if you have fixeed blad boadheads make sure they are tight and in line with your flecthing . and try it again if the same things happens . you may want to asure the flec is not hitting the rest in anyway . then paper tune your rest . to asure it dose not tear the paper in any direction and it only make a clean hole .then rest your sites .
I have noticed the same thing on a couple of my shots, but I figured that it was just me.
your fletching is most likely hitting your rest.I would try a heavyer brodhead.
if arrows fly true and straight with field points,change weight of tips and heads, try diff broad heads.my arrows are 2413 and 28inch long,use 100gr thunderheads and fly true,i paper tune from 1 yard away,dont know of anybody that sets up that close,my arrow comes off my bow straight. to get max velosity i want the arrow flying true as soon as it leaves the bow. try paper tune real close and see how arrow comes bow. just a thought.
My suggestion is to go to an archery store and shoot with a bunch of different rests until your arrow flys true.
build good rapor w/ your local archery pro!! it'll be one of the best archery investments you'll make
