If they're too small let me know, I'll try to make them bigger.

Your arrow tip is tracking left and a little high from the nock. Assuming the arrow spine is correct and you don't have a clearance problem; you would want to move the arrow rest to the left about 1/16" at a time and also raise you nocking point a little. Just be advised that the classic "too stiff" of an arrow shaft tear is what you have. It is also commonly a sign of the fletching hitting either the arrow shelf, launcher, or the buss cable. Don't start moving anything until you have completely eliminated these two possibilities.

Could I lighten up on the poundage to rule out too stiff a spine? I'm shooting acc 3-39s at 27.5", 100g heads, at 70lbs. '05 ally with 27" DRAW.

RE: paper tune pics, whatdya think?
 

That will make too stiff of a shaft even worse. You could just strip the fletching off an arrow and see where it hits at 20 yards compared to a fletched shaft. Do this with field points, not broadheads.

Also, give us a rundown on your setup. What bow, poundage, arrow length, arrow brand and series, point weight, etc?

RE: paper tune pics, whatdya think?
 

Duh! Of course it would. Dunno what I was thinking. How about if I bare shafted it thru paper? Would that show fletching clearance problem?

See above post for specs. I edited it.

Well, the Easton chart shows a 3-39 to be on the weak side. You should be using a 3-49 and possibly even a 3-60. Backing the poundage off to about 65 lbs. will likely help the spine issue, but will also probably make the left tear worse. No contact issues over on the right side of the arrow? Then I would move the arrow rest to the left and see what happens.

I had a brain fart, they are 3-49s. I went and shot a bare shaft thru the paper and got the same diagonal tear minus the fletch. Is moving the rest my next step?

RE: paper tune pics, whatdya think?
 

I ended up moving the rest almost 1/8" to the left but have a good paper tear as far as left right goes. It still looks like it is a hair point high though. Is my only option to move the nock point up?

RE: paper tune pics, whatdya think?
 

You could also lower the arrow rest a little. And, while you have a shaft with no fletching, you might shoot it at 20 yards and see where it hits relative to an identical fletched shaft. If it's angling into the target to the right of the fletched shaft, the spine is too weak.

If the centershot LOOKS good,then you may have found the problem,if the centershot is off,then it is quite possibly a torque or spineissue now.


You should be able to adjust the rest vertically to fix the vertical tear.

RE: paper tune pics, whatdya think?
 

If you are planning to hunt with it I would go ahead and screw on some blades and broad head tune it from there. If you are just going to shoot field points I wouldn't touch it, or move on to group tuning if you want to fiddle with it. A lot of people aim for a high left tear on purpose, and yours looks pretty consistent which is good. I would say you have it close enough to move on to the next step of tuning or leave it alone and work on shooting. It is tuned plenty well enough to be accurate with target tips.

Wow, I got the tuning gurus helping me out, I really appreciate it guys. I'm gonna try and post some of the "new" paper pics(bare and fletched shaft after the rest was moved to the left). I just got home from work and its getting dark so shooting out to 20 tonite is not gonna happen. To me it still looks like I have a point high tear, I guess I should either drop the rest slightly or raise the nock point. Which would be the better solution?

After moving rest 1/8" to the left

Assuming your arrow is right down the middle of the Berger hole in the sight window, I would generally prefer to raise the nocking point. Sometimes nocking points don't want to be raised, though, after a couple dozen shots - so you could either tie in a new one or lower the rest a little.

Once it tunes, go right into seeing where fixed BH's hit relative to field points. May wind up having to move it again.

RE: paper tune pics, whatdya think?
 

Make sure you are doing it at different distances.;)

RE: paper tune pics, whatdya think?
 

Yes - once you successfully get things reasonably "tuned"; carefully read T Fox's tutorial at the top of the Technical section "Don't Stop at Walk Back" - lots of great info in there about fine tuning the setup to your shooting style. Has helped me a bunch on several occasions.

RE: paper tune pics, whatdya think?
 

You could move the rest down a tad. That will accomplish the same thing as moving the nock point up.

RE: paper tune pics, whatdya think?
 

Nocking point up or rest down, whichever is easier. Keep in mind about broadhead clearance with the shelf.

Something I learned a long time ago. Always make your vertical adjustments first.

Are you using Easton's Tuning Guide? If so read the next to last paragraph at the bottom of page 13. Your right tear should mean a stiff arrow, but release shooters may get an opposite reading. Don't ask why, but it happens to me, proving that nothing is written in stone.

RE: paper tune pics, whatdya think?
 

Update. Finally got to shoot outside. Had to first move my sight over because of the rest being moved. Got fletched field points stacking up at 10. Then shot unfletched and it was about 1/2" off. Pretty good I thought. Moved out to 20 with same results, unfletched off by about a inch. Screwed on a brand new G5 stryker, and right thru the X first shot! I never bothered to address the point high tear, yet. I will be doing more experimenting but I'm almost afraid to mess with it, you guys got me REAL close to where I wanna be. I will be shooting it out to 40 or 50 just to see how good it is, but as it is I cant thanks you guys enough for all the help.
