In this pic the shot you see is what I keep getting. Any suggestions to bring the fletched shafts and the bare ones together. I am shooting a Mathews Ovation at 70 lbs, 30 inch draw. Goldtip XT 75/95's at 30 inches, 100 grain tips.
The fletched arrows at all distances to 50 yards will hit nock right in the target.

Thanks for any help!!

Hard to tell at that angle. But if the bare shafts are hitting pretty straight, then the vanes are probably hitting somewhere. That could cause the tail right, and the different groupings.

Makes sense. Do a powder or lipstick test.

I agree that with the camera angle it's hard to be precise, but I think I have a general idea here,, Bare shaft is hitting to the right of the fletched arrows, Your arrows are acting stiff. You got a couple choices. Raise the bow weight, get heavier points, lighter spined arrows.

Now maybe you don't like any of these, or can't add draw weight. Whatever, you can use heavier points to at least see if this helps bring the two arrows together. If it does then you know the arrows are acting stiff. If they get worse then you know to go the other way.

Hoho...

Bare shafts hitting right means weak arrows...

0 fletching contact. Checked that first thing. I was told 75/95 would be what I needed. It will shoot the same from 20 to 40 yards. Would moving the rest help?
Thanks!

My experience with bare shaft tune has always been that arrows fly straight, tubes shows the problems - and not the other way around! :confused:

Your arrows are acting a bit weak, the nocking point is a bit hig (or cams may be a bit off time).
I can't see how this would make they fly slanted and the tubes not.

A question - at which distance you've shot the arrows for the photo?

15 yards

Are the bare shafts straight, or at an angle like the fletched ones? I can't tell by the picture. Michael

They are at an angle but not as bad as the fletched ones.

Try a 55/75, see if it makes a difference.

For 15 yds the distance betewwen arrows and shafts indicates weak (if this was at a longer distance, it just could be that the tubes are weaker due to the absence of weight in the nock side - vanes).
If you want to double check, add some tape (insulating, etc) to the nock side until shafts have the same weight as arrows.

But this still doesn't explain the slant...

Wait, if the bare shafts are slanted also, adjust your center shot until they aren't any more.
Then let's worry about arrows.

Tail left - move rest to the left (for a right handed shooter) or vice versa.

I agree with jorge. Also at 70lbs and 30" with your bow the 7595's should be alright. But if you have some 125 grain tips lying around that could soften them up a bit. Michael

Bare shafts impacting to the right of fletched arrows indicates a weak arrow...

If the difference is only a couple of inches it will be ok... if it is more then turn the bow down a couple of turns and try again... this will easily tell you if it is centershot of spine... if you see no improvement when you back the weight down, then move the rest as Jorge indicated... if you see improvement... and can't lower your tip weight... cut a 1/2" off the arrow and try again...

Jave, you took the words right out of my mouth! If it's spine, just cut a little off one of the arrows and see if the bare shaft and fletched shaft come closer together.

Thanks for the help!! I wll work on it Saturday and see what I come up with. :smile:

cheaper way to tell for weak shaft..
change your tip weight...
try 85 then 75 just to see.

Ok guys, it is definitely weak shafts. changed the 100 grain tips to 75 grain and cured the problem.

Ok I bought the bow at 70 lbs because that is what I want to shoot. Another problem is I wont be shooting 75 grain heads they will be 125. How much would this arrow have to be shortened to be usable or would it just be best to look at some other arrows and if so what would you recommend?
Thanks!

To use the 7595 with 125g BH + inserts, your max lenght should be 29", 28 is better.

If this is too shotr, look for a spine 300 arrow, then 30" shall be fine.

Does Goldtip make a 300 spine arrow?

Idaho_Elk_Huntr
March 19th, 2005, 12:42 PM
according to the goldtip chart the 75/95 is a 300 spine arrow

Jorge Oliveira

Idaho Elk Hunter:

If you cut 1/2" to 3/4" off the shaft you should be able to use 125's with no problem. I'm guessing 1/2".

So how would you guys explain the fletched arrows slanting?

Does this indicate a weak spine or more of a center shot problem? My fletched arrows are doing the same thing except they are slanting to the right when you look at them.
