I am shooting a Hoyt Vtec (2005) @ 63 lbs., GT 5575 XT Hunter 27" with 2" blazers, 100 gr. field point, Draw length 27", Quick Tune 1000 rest.

I noticed while shooting staight on at the target, that from 20 yds. out to 40 yds. that the tail (nock end) of the arrow was leaning to the right in the target. It is barely noticable at 20 yds, but very pronounced at 40 yds.. The point of impact is slightly off, approximately 1 - 2" left when I shoot at 35 - 40 yds, but dead on out to about 25 yds.

What is up with that??

Screw in 125 grain field points,
and add a full turn to both limb bolts (upper and lower).

You will be adding roughly 2-3 lbs to your draw weight.

The extra weight in the tips
and the extra draw weight will weaken the arrow stiffness.

Your arrows are too stiff for your application.

Nuts & Bolts

I will have to swing by the sporting goods store tomorrow to get some 125 gr. field points. Does this mean that the (6) 100 gr. Rocket hammerheads are no good or can upping the poundage to 65 lbs fix the issue?

If the bow paper tunes it's you! I had the same issue. You are not under/over spined or off on foc, you are torquing the grip. 100 grains is more than adequate on a 400 grain total arrow.Work on your grip. If you dont believe me allow someone else to shoot the bow and see if it changes.

Hello there medicFF:

Since your shafts are only 27" long,
they are actually rather stiff.

If you want to use the 100 grain broadheads,
you may need to bump up the draw weight all the way to 70 lbs.

Just keep cranking the limb bolts and increase the draw weight.

You should see the groups getting better as the draw weight goes up.

Otherwise, switch to 125 grain field points and broadheads,
and again, experiment with draw weight to find the sweet spot.

My guess, somewhere around 65 lbs, should be right
for 125 grains.


Remember to keep the bow hand,
and bow fingers relaxed, soft and mushy
(thumb muscle needs to be mushy).

Sounds like the center shot may be off a bit.

Thanks everyone for the input

When I had the bow set up at the local pro shop, the bow technician had it shooting a perfect bullet hole on the paper. However, I never could get it to quite shoot the hole that he could. So, I guess it could be me torquing the grip. Could it be that I'm canting the bow to one side slightly?

I am going to try bumping the poundage up slightly as NUT/BOLTS suggested to give it a try.

Thanks for all of the advice.:wink:

Hello Glen:

When an arrow is rather stiff,
a perfect bullet hole is still possible,
but the form must be perfect.

If you bump up the draw weight
and go to a heavier tip weight
(next size up),
then the dynamic spine will be closer to
"proper range"
and then the arrow will behave
correctly and be more "forgiving"
of small form errors.

Adjust the bow, so that
the bow performs well for you
and
not the other way around.

What type of target are you shooting into? A bag style will sometimes get arrows leaning due to the stuffing inside is uneven. If your groups are a 1-2 inches at 40 yrds..that is still good shoot'in. If your target is fixed or in the past you or others have make straight groups... then try the 125 gr. idea and more poundage.

Its a new compressed layer target. NUTS/BOLTS, I just bumped the poundage up to 66 lbs along with trying to really concentrate on my grip and it definately improved. It is not perfect yet, but it is better. Bumping up the poundage just 3 lbs created a noticable difference in the pull, which I will have to get used to.

Thanks

Glad to hear that.
If you try the heavier points,
at your new draw weight,
that could also tighten up the groups.

A little change here.
A little change there,
can make a huge difference in your groups.

Now, if you really get bored,
we can then talk about "creep tuning".

(hehehehe).
