What type of rest are you using ?
How do they (broad heads) impact and group in comparison to field points ?
Personally I put little value in paper tuning. I've seen way to many contradictions over the years to put much faith in it, perfect tears grouping terrible and perfect groups with less than perfect tears. To many variables.
Proceeding slowly and one step at a time the answers to the above will help us get a solution rather quickly.

using qad ultra rest. everything groups very close together. but still can see a little tail wag with the broadheads. going to try again thursday after i get back home. always take things slow thats why i wrote this to get anything i'm missing. thanks jeff

Not at all familiar with this rest by name. Does it have vertical spring pressure/tension like a prong TM Hunter style rest ? If so the tension may be a bit to heavy and it's kicking the back of the arrow up as it leaves the rest. If it does have tension adjustment it should be set just barely heavy enough to support the arrow when at full draw. It actually should drop a fair amount with an arrow nocked and bow at rest and then spring upward as you draw, almost like a fall away rest. Also how long are your arrows, how far do they stick out in front of your rest ? Ideally they should not stick out more than 1". I've seen this cause this problem numerous times. Arrows slightly too long and since a broadheads weight is distributed over a longer distance than a field point it compounds this issue and causes the shafts tail to "kick" as it clears the rest. We'll get it Bud. Just glad to see I can count on you to be one of those that doesn't wait until the last week of September to check broadhead tuning..

the qad ultra rest is a fall away. first you put the arrow on then you load the rest by cocking the rest in the up position. this locks the arrow in place like a w.b. when you draw it pulls the rest up to full. then when the arrow is released the rest falls away and locks in the down position no bounce back. the rets is clamped to the down cable to run.

OK, so it takes inertia to drop or fall away. Is there an adjustment for just how much inertia it takes for it to fall ? If so this may be set a bit heavy kicking the back of the arrow up.
Whats is your draw weight, length, and arrow type etc. ?

sorry need to explain more the rest is locked up when you pull it back the last inch cocks it back and the speed of the return allows it to go down where it locks down. no adj. on the speed draw leght is 29in. 65 lbs and 340 easton fmj 28 1/4 inch. checkout the rest at www.qadinc.com.

Went to their web site and read their tech section. Seems that from what I understand the amount of tension on the cord controls how fast and when the rest drops. They say to much tension here is better than not enough. I'd try moving this slightly and see if it changes anything.
Wish I could see the rest in person as it would help figure things out but I can't convince myself yet that it may not have to much upward tension on it causing the tail to kick up from the oscillation of the arrow before the rest drops and/or the arrow clears the rest.
One thing I didn't ask, do you shoot release or fingers ?
Another way to check is try another rest if you have one. If problem goes away then you know its the rest.

shot with a release. was waiting on a drop zone but they didn't come out till recently. will try the idea and let you know.

Just checking another thing Bud do you shoot with a relaxed open hand and a sling ? Just trying to rule out that your torquing the grip as this can cause this problem as well.

Jeff,I don't think his problem is with the rest kicking back up.That can happen but it's a rare occurance and it would most likely show up with his fieldpoints.Assuming,the broadheads are spinning strait,it could be a bunch of other problems.How much helical are you using?What kind of vanes?WHAT'S YOUR FOC %.Your cams could be leaning which isn't uncommon for Bowtechs.Touquing the grip may very well be the problem.However,if your broadheads are hitting where you want every time,I'm not sure I'd worry about it.Your eyes may just be playing tricks on you.It's pretty tough to concentrate on your shot and also see the arrow flight at the same time.If you can do that,I'd say your lifting your head,which is most likely causing you to tourqe the grip.

use a sling and an open hand. the rest locks in the down position so theres no bounce. may have found the problem was using a bow square and a string level. well it dawn on me the diameter of the square is different than the diameter of the FM all the marks on the square for where the nock should be is larger than my nocks on the arrows this gives the impression that my nock is below 90 degrees. will try some more tuning and let you know.

OMG dougell it's funny you mentioned the things you did as I was heading there eventually, just proceeding very slowly.
The peek issue, I've seen this so often that I've even had a few people that to prove to them this was the culprit I blindfolded them and had them shoot thru paper at close distance. Perfect tears yet without the blindfold the tears were less than perfect. The shooter is so concerned about either arrow flight or where it's hitting their peeking.
Why do we try our broadheads out ? To see how they fly and if they hit with our field points. How do we see this ? With our eyes and it's much easier to see if as you release you pull your head away and peek.
I've also found this to be true with MOST peekers. Right handers will hit low right while lefties hit low left. As they pull the head away to peek the bow arm goes down and in the opposite direction of the head.
