Walk Back Tuning Using a Whisker Biscuit Arrow Rest.
Ok guys got out in my building and was trying to paper tune my bow. If you stand 6 to 8 feet from the paper and shoot it has a bad tear to the right. I tried adjusting my rest and it dosen't matter how far you move it, it will not go away. If you move back to 15 to 20 yds it will have a slight tear to the left. Could it be that it is fish tailing? That is all i can guess. I am shooting a whisker biscuit rest. Some say they don't paper tune well but some do. What do i need to do? Thanks!
Paper tuning should be done at 6 and 12 feet, no more, no less..... Since your getting a severe tear, take a bare shaft (no vanes) and put a field tip on it. Then shoot it thru paper at 6 feet and 12 feet... Remeber to "follow the tear"..
If the paper is tearing to the right, move the rest to the right... etc..... "follow the tear"
You should be able to get a bullett hole pretty soon...
Once bullet hole is achieved, then shoot a fletched arrow, If you don't get a bullet hole, play with the nock on your arrow... adjust it several different ways to try and achieve a bullet hole.. after that, index all your arrows so you get a bullet hole out of each of them....
Biscuits are probally the easiest rest to paper tune IMO.
Your Definately Fishtailing. Are You Right Or Left Handed? Most Likely Your Shooting An Arrow That Is Under Spined. For A Right Hand Shooter If Your Tearing Left Move Your Rest Out. (left Hand Move It In.) First Thing Id Try Is A Different Arrow (heavier Spine) If You Have Several Different Sizes Try Em All Just To See.
I would paper tune to get the nock point set (up and down tear) and then do a walk back tune.
Set up a target with a dot near the top and a plumb line running through the center of it that extends all the way down the target.
Now from about 5 yards shoot a group at the dot with your top pin. Obviously your windage needs to be properly set on your sight.
Back up to 30 or 35 yards and again using your top pin shoot a group aiming at the dot at the top of the target.
This group will obviously be lower than the first group but should give you an indication of where your center shot is set.
We are looking to get the two groups to be perfectly vertical "I". If they look like this "\" move your rest to the left. If they look like this "/" move your rest to the right.
Continue until you find the setting that consistantly produces the perfectly vertical line between the two groups and you have your centershot set pretty dang close.
Only count the "good" shots and always do the test two or three times before moving things around too much.

Didn't think about that. What are the specs on your rig and what arrow are you shooting?
Another Consideration Is Contrary To Popular Belief...."a Bullet Hole" Is Not What You Want. A Right Hander Needs A Hole That Tears Very Very Slightly High And Left. This Gets The Back Of The Arrow Up And Away From The Rest As It Leaves The Bow. Only About 1/4" Max Off Of A Center Bullet Hole Though.

Tuning-Tips
I keep getting a high tear when I paper tune my bow. How can I fix it? Most single cam bows still have a little vertical nock travel during the shot. This can result is a slightly high paper tear. If your bow is set up with even tiller, and the arrow rest is positioned so the arrow passes by the anchor bolt hole, and you are getting a high tear of 1/4 inch or less, then this is a satisfactory setup with the Whisker Biscuit and will result in good groups. There are however several things to check when you encounter a high paper tear. They are:
Biscuit gripping the arrow too tightly - If the wrong size biscuit is being used for your arrow, or if the biscuit is not adjusted correctly and is fitting too tightly around the arrow shaft, a high paper tear is likely. To correct this problem verify you are using the correct size biscuit for your arrow. Then if necessary, adjust the biscuit by spreading it open at the split until the arrow passes freely through the biscuit. A loose fitting biscuit is optimal.
String Nock Point too Low - The string nock point should be adjusted so that the arrow lays flat across the riser and passes in front of the anchor bolt hole. It is better to have a slightly high nock point (1/8 to 1/4 inch), than a slightly low nock point. A low nock point can produce a high paper tear.
Incorrect Spine - 2 cam and 1 cam bows seem to differ as to how they respond to spine. Here is what you will typically see:
Two Cam Bow - A high spine weight will cause a high tear. In general you won't see a low tear.
Single Cam Bow - A high spine weight will cause a low tear. A low spine weight will cause a high tear.
Disclaimer - There are many different cam designs, each with its own personality. If you find that the above observations don't pan out, try the opposite. If you are getting a vertical tear you can't get rid of by adjusting the rest or nocking point, it is a good bet that the arrow spine is the issue.
Biscuit too far to right or left - Occasionally a vertical tear can be corrected by moving the biscuit to the right or left a slight amount. If you notice that your vertical tear leans to the side, try a slight horizontal adjustment.
Cock Feather Down - Depending on the string nock travel path of your bows (determined by the type of cams) the cock feather can come in contact with the bracket at the bottom of the biscuit. To eliminate this potential contact you can do one of the following: If you have tunable nocks, turn the fletching so that it clears your cables and riser. This will move the nock away from the bracket at the bottom of the biscuit. For fixed nocks, simply turn the arrow over and shoot with the cock feather up.

oh, theres the problem.... you need a MATHEWS!!! just kidding. you should be fine as far as arrow spine unless your shooting a super long arrow. (30"+) is it a one cam or two? if its a two cam your timing may be out. (both cams turning in unison w/ eachother)
Thanks guys i am going to work on it a lil more today and see what i come up with. I will let you know. P&Y i hear you on the bow but i told myself i wasn't going to buy a high dollar bow till i started killing some with what i had. I went from a PSE nova to the Gtx so that was a step up 
) If i can get it tuned it will be anyways lol.
Well it is getting better guys got out there for a min while ago before i had to come in to get ready to go to work. With bare shaft it only has a small tear now after adjusting it some. Hopefully will have bullet holes in the morning when i get out there. Then try to shoot a fletched arrow and see if i have got it.
Good Deal!! Just In Time Too. Two Weeks To Spare. Good Luck.
Yeah it isn't that it wasn't shooting ok. I just wanted to know that it was shooting as good as i could hold the bow. And it is not a equipment problem if i shoot bad i know it will be me.
Well guys finally got it paper tuned. Rest was way off. After playing with it and tweaking a bizillion times she was shooting good holes through the paper. Well then i went out to shoot it and didn't think about readjusting my sights. Well first shot at 20 yds buzzed a arrow right past the target hit the ground skipped through the woods and is yet to be found
