As you know there are a ton of things that could result in your arrows grouping right...all of a sudden like.
But if the only thing that you have changed is the tab face- then we have to consider that the string is 'coming off the tab' faster- putting ( or allowing ) more ooomph and therefore bend into your arrow, don't we?
Was the group a little higher too? if yes then this is likely it!

Other factors 'around' the tab- like your hook or release may also have been affected by a thicker/thinner material now being used- or perhaps even the material supplied is somehow different to the material you started with?
( I know when I tried oberon it 'seemed' to stiffen my arrows ie: they went lefter -I'm a righty)

Go back to your original facing to see what effect that has....also go through your form, stance, hand position, head position, alignment, release etc etc It may well have a been a one off, odd shoot where you were doing something odd.

But for my money- I'll bet on the new material being a little slicker/faster/less sticky than the old face, enabling a cleaner release....more ooomph into the shaft on release- and thus a 'seeming weakenning' of the arrow.

Either that or something in your release hand or hook is making the string come off at a steeper angle than you are used to- more side to side oscillation in the string as it travels to is nock detach position- and that this alteration in the nock detach point is 'kicking' the back end of your arrow out- sending the arrows over to the right.

Tab facing can have a Major impact on the tune of a bow.
I'd suggest Really studying your release hand for a few ends- ensure consistency- and re-tune your button position and pressure for a good walkback result while using the new tab face.
Start with brace height...you may find that merely a few more twists on the string will correct and center your arrows. ( or less even )

my sight is now wound quite far in (R/H'er by the way).

im going to try and check the bow sight alignment later today, but i have a feeling its ok, so any other ideas peeps?

could it be that the arrows are the wrong spine? i know they used to be a little on the stiff side?

thanks in advance

Hi Al,

If we are talking about the same set of arrows, then FWIW I reckon you've benefited from a cleaner release, less drag from the tab so a shallower angle as the string goes round the fingers - hence further right but same sightmark. I think.....only think.... that its time to fiddle with the button a bit. Maybe....put the sight back vertically over the arrow and see if it will correct with a slight change to tension (or even moving the "centre shot" a bit further out).

Or not... of course. Are you getting the elbow further back?

if your arrows are comming out stiff, i would not change them yet. wait till you get your hex5's, the extra speed may bring them into spine.
thats assuming you don't have them yet

Agree with KC & Geoff about the tab. First thing I would have done is shoot using the old one.

Then check that everything is screwed down correctly especially the button and the centreshot has not moved. Next check your limb bolts are tight and limb alignment has not changed.

After all that check your arrow clearance you might find the back of the arrow hitting the riser - this will make your arrows go right (RH archer) and could be a result of the tab.

hi again all

yes im have not got the hex5's yet, and was planning to change arrows when i get them - an added frustration in waiting for them.....

i will check the arrow tune again tomorrow but maybe its just because i have a cleaner loose with the new tab facing. its odd though becuase i have changed oberon before without any noticeable side effects???

will inevestigate more tomorrow when i can shoot properly.

have just spent the day looking after a hen party have-a-go.

its a hard life....

You don't have to suffer alone Al - you can rely on my support. In fact I'll put it in the post now!

hi pete,

not shot new limbs yet as they have not arrived. button is never removed from the bow, and i have checked it all over, button seems to be working smoothly and all is where it should be - all seems good.

have sinced moved the centre shot further out, and i have adjusted the sight to see if its anymore square to the bow.

new limbs should be here next week (fingers crossed...) so will see if there is any difference there.

incidently when i shot at 30m, before i adjusted anything the arrows were going to the LEFT (opposite of 70m). this lent me to belive it maybe sight related but im not sure??

I've gotten so confused here- i dont know what limbs, arrows, tab you're using now.......but stop changing stuff for a bit pleeeease.

But it sounds like a walkback test is in order from 20y-80y- in fact three walkback tests would be better...carefully and paced out arrows- shot to your highest standard....with exacting handplacement and form- and your cleanest releases.

and the resultant line (or expected 'squiggle') of your arrow fall described to us.

PS Im not surprised that your moving centershot has shifted close range arrows left - i expect your long range arrows will still be right- likely more so.

hi KC,

just to clarify the only thing i have changed is the tab. i think the others who have commented (and thanks for doing so) have got a bit confused.

im due to be changing limbs, and arrows to match, soon but not yet.

cant hsoot tonight but maybe will do more experiments tomorrow.
