Great groups but 4-6" high
« on: April 20, 2009, 11:05:00 PM »
Not sure what the deal is but with my new t/d longbow I hit consisitently high EVERY time. It is a little faster than my other bows but not enough to cause this much of a change. Same arrows of same weight

It's as if the bow has a mind of it's own! Even when I really burn a hole in a spot I still shoot high. If I back out to 25 or 30 yards, it's not uncommon for me to shoot over the target. I normally shoot from about 15 yards and it is almost impossible to hit lower even though it appears that I'm aiming lower. Brace height looks good, so does nock set. It;s about 1/8" high.

My guess is your nock point is to low. I'd start at a 1/2 inch and work up or down fron there. Did you bare shaft tune?

you need to move your nock set higher.

Moved nock up but arrow  still hits very consistantly high. I just shot 30 arrows and every one was high about 6". On my deer target I am aiming low behind the shoulder but hitting just below the spine. Even if I back up to 25 or 30, I still hit high.

I'm going to bare shaft tomorrow.

try working on your follow thru and bow arm steadiness.....i wonder if there is a chance you might be slightly raising your bow arm at release..

New bow, maybe its the grip thats too low? That would be my guess if the nock set is not fixing it.

I can move the nocking point up and down and it makes no difference in where I hit. I have three bows that are from the same maker but different years and he made the risers a little different and each hits a little different in elevation.Tried to tune them in moving the nocking point with no effect!  Ben

A friend of mine shot this bow for the first time and also hit high within an inch of where I was hitting. The shelf is about 1/4" above my fingers.

Well it's either a tuning issue or a form issue IMO.

Is the draw weight and/or arrow weight lighter than waht you're used to? If that's the case you might be drawing it further.

Is the grip different? A certain grip can create more pressure on the lower end of the bow (or a stronger lower limb) and make the bottom limb stronger which can in turn create a low nock reaction and a higher impact.
One man thinks he can, the other doesn't. Both are right!

I checked the tiller, it is 1/8" stiffer on the upper limb. Draw weight is about 65lbs(what I normally shoot)

How long have you had your bow? How many shots are through it? Do you not use any aiming reference to the arrow point?  Do you shoot both eyes open?

Jim,
I mean no offense but the problem is probably you.  Forget what your friend did because it wasn't the bow he was used to shooting either.  You noted that the arrows are flying faster from this bow.  I think that is your answer.  Higher speed makes more difference than you might think.  I recently had a friend over who is a heavy arrow fan.  I let him shoot some of my much lighter arrows and he was putting them high, sometimes over the top of the target.  His brain wasn't programmed for the lesser drop of the faster arrow.  I think you are probably experiencing the same thing.  Spend some time shooting and you can reprogram yourself.  Either that or get some heavier arrows that will come closer to the slower speed you are used to.

Limbs are reverse tillered.  Turn it upside down and shoot it off your hand (seriously) to see if there's a difference.  Lower limb (not upper)should be stiffer to compensate for its longer working length to balance the higher-than-center-of-bow arrow rest. The limb closest to the string is the stiffer limb.

Stop aiming with the tip of your arrow.
