clearance problem ? form problem ? any ideas ?

[pHz]

only noticed this at the end of my practice session this morning and had no spray or anything with to check clearance (will do so tomorrow during the sighters for the competition im at)

my horizontal grouping has been a bit off for a while now but it wasnt until today that i noticed for (at least) the last 2 ends this morning EVERY arrow (and so by extrapolation every (?) arrow ive shot recently) was exhibiting the same behaviour in flight - kind of a half-fishtail - about 5 meters after leaving the bow the back end of the arrow kicks VERY noticably out to the right before straightening up and then flying straight (no more fishtailing) on to the target

(right-handed archer)

i have two thoughts on this -

1 - its a clearance issue but if this is the case im confused as to how the arrow is kicking out right (ie - into the bow rather than away from it as id expect if it was contacting something on the way out) - what contact could possible be causing this ?

2 - something in my release is causing this (the only club coach available had already gone home by the time i noticed today so couldt get it looked at) - is there anything i could be doing that might cause this movement ?

what puzzles me (and makes me think its a contact issue) is the fact that this movement in the arrow is a single one - once the rear of the arrow has kicked out and the arrow straightens up it flies straight and clean (no fishtailing or porpoising) but has obviously been knocked off course by that point

im as confident as i can be that the arrows and bow are matched in terms of poundage and spine so i dont think thats an issue

only other thing is ive recently refletched with quickspins - should i have the nock set differently for those ? and is there any way they could contact the arrow rest that would send them 'into' the bow rather than away from it ?

obviously i can check for contact and get someone to look at my action but wondered if anyone had any ideas as to the areas i should be looking at first

If its your horizontal ( ---- ) grouping we are looking at, it shouldn't be anything to do with your nocking point. As for the contact point have a look on your bow and see if there are any tell tale marks, also like wise inspect your wings for marking folding! Have you checked that your center shot hasn't changed/moved in any way?
Also are you getting a clean release leaving your fingers in there or touching the arrow on release could force the arrow further than normal by bouncing off of the button!

no marks on riser or arrows / fletchings (will check with deoderant or something tomorrow though to make sure)

centreshot is fine

as to the release thing it might be but if its "bouncing off the button" then surely it would bounce away from the bow (ie - to the left and not to the right as im seeing)

Right handed. If your string is not clearing your tab correctly the rear end of the arrow will go left slightly on release sending the arrow right off of the button! It doesn't have to be a lot but it may be obvious if you film your release at your hand and from above. If doing it digitally this can be moved forward frame by frame, high speeds are best for this! As for the arrows if they are contacting the bow on the way out you will see some sort of wear or "shine" to the two fletchings closest to the bow. If nothing on the bow has changed I would say it may well be a release problem. Hope this helps

Just a thought it could be that you are moving the riser or it's twisting it on release. Or unknowingly trying to peep to see the arrow in flight. Did you observe the kick or was it a fellow archer.

i dont THINK thats the issue

maybe i didnt explain the movement im seeing clearly enough - the arrows themselves arent going right (in fact theyre ending up left of aim if anything)

what happens is the arrows exit the bow but after about 5 - 10 metres the back (fletched) end of the arrow kicks out to the right (the tip of the arrow still travelling FAIRLY straight) before coming back into line again - the best parallel i can think of is the movement of a car in a rear wheel skid - the whole thing is still moving forward in its line but at a diagonal angle to the direction of movement before it straightens up again and flies STABLE to the target (although the movement MUST surely be affecting where the arrow ends up) -

both

it might well be something im doing though - as i said just fishing for ideas of things to look at before i try to sort things tomorrow

The half fishtail 5 m out from the bow could be that the lighting on the day allowed you to see the glinting from the second half of the oscillation. Perhaps the in first half the glinting was aimed away from you. It would seem strange for the movement to start 5m away from the bow. If it is a lighting thing, the first half of the oscillation would be away from the riser as if contacting something.
The cause could be the new fletchings, perhaps they need to be rotated a little to clear properly. It could be that as you tire you torque the bow a little causing the arrows to fly as described.

do a walk back from one to ten meters, see how the arrows impact the boss, this will give you some idear whats may or may not be happening.

What your indicating is the usual trait of a week tune, loose some point weight of drop your poundage. or indeed move your centre shot out still further. If the Nock end didn't flick out and just the point travelled to the left it would be a stiff arrow reading
