I seen a post on here before but I can not find it. I noticed when I shot my lighted nock today at 30 yards it looks like it does a little fish tail action. It doesn't look like the fletching is hitting anything but I could be wrong. I am shooting with a drop away rest. What could be the problem?
JMO, you don't have any problem, normally the arrow do a litte fishtailing that is not visible without high speed camera, in your a lighted nock highlighted the movement.
If you don't think that it is a vane issue then it might be a spine issue. If you don't have a stiff enough spine for your # then when the string is released the arrow will bend coming out of the rest and this could cause it to fish tail. I would check your vanes though. Twist the nock a little each way just to make sure. I have a dropaway and could tell that my arrows were fish tailing so twisted the nock a little counterclockwise and they don't fish tail anymore.
What are the specs of your setup and arrows? I could be a spine problem or a tuning issue. Shoot us some more info and we can get you fixed up. The arrows are very erradic but should be relatively straight during flight.
I have a feeling you're under spined with 400's on a 70.5lbs draw weight. What's your DL and how long are your arrows?
I agree with REM - seems like you may be a little light on the spine side... Beyond that - we're kinda shooting in the dark without looking at it.... There are many things you should try and verify. For example: - Have you paper tuned your bow? - What type of vane and configuration are you shooting? For example I've seem quikspins do some weird things depending on the bow/setup, if your vanes are near straight - I've seen arrows act almost like knuckle balls, etc. (try shooting an arrow that has more offset or a helical) - You said you have a drop away - is it setup and timed properly? - Is your center shot correct? - Is your nock point corret? - Is your arrow properly spined (try a stiffer shaft in your case) - Is your bow in spec (axle-to-axle, cam timing if appliable, etc) Unfortunly there usually isn't a smoking gun, you just have to start narrowing potential problems until you find the root cause. Good luck!
Under spined and not enough weight would be my guess. You may want to also move up to a 125 GR head with that poundage. I have found over the years its better for FOC to be on the high side.
Thanks a lot guys for the information. I picked my arrows by using the poundage chart but I will look into getting new ones. Thanks again.
If he's already underspined, increasing BH weight is going to exacerbate the problem. Granted, FOC is important, but if you're shooting limp noodles, it's a dead issue. Sent from my HTCEVOV4G using Tapatalk 2
I may be wrong, but I think Heckler was advising the op to go to a stiffer spine and up the weight/ FOC.
Ah! That makes sense. On a related note, I'd suggest paper tuning with the current set up. Chasing a stiffer spine with a bow that isn't tuned properly... Man, talk about frustration. Sent from my HTCEVOV4G using Tapatalk 2
