String jumps bolt.

Dennis · Post by **Dennis** » Wed Dec 08, 2004 10:27 am

String has jumped the bolt a couple of time, anyone know what causes that?

Bolt must be fully seated back against string before fireing, not just under hold down. Maybe?

what is the shaft that makes up your bolt? 2219? Laser II?. I suspect its due to being improperly seated since the excalibur is a top release claw. this sort of thing is more common on a bottom release claw such as the horton bow

DyHard reads right...sounds as if you are not against the string with the bolt. Are you using the proper size bolt/arrow and are they flat nocks/inserts in rear

Gary is absolutely right about the flat nocks!
When I first got my bow,it came with 4 bolts with moon shaped nocks.
I had a couple of jumps,and erratic flight.
I filed down the ends to be flat,and the problems all went away.

You guys are amazing, 2 replies in a few minutes.

I know that if the end of the bolt does not contact string it could jump, but this happened two shots in a row, being human, I could possibly not set right the first time, but know I would focus much more on the second.

The string brace height is off a bit, will reset that, how bout lubricant on the string?

Since I bought the bow, (Exocet), there has been a burning smell after shot, but have been told that is normal.

Thanks!

there has been a burning smell after shot, that is a norm...

If you are shooting the right size bolt with flat nock, then check and see if your riser is tight. Check all bolts to riser and limbs, then if that don't work e-mail Excalibur or call them.

One more thing are your bolts straight

I get the burning smell off of my Exomax all the time. Nothing to worry about.

Forgot to mention, 2219's, and ground flat nocks.

the burning smell is what happens with the anodization on the aluminum bolt subjected to friction. Moon nocks will WORK if positioned correctly-they were designed to correct the rare jump that happens with the bottom release Horton bow.

I tell even horton shooters (I was one once

) to use the flat nocks -its too easy to put the wrong vane down in the track and have your moon in the wrong position.

never heard of too much lube causing this and I have been shooting xbows for 30 years.

I had ONE case of this-yep-the bolt wasn't seated firmly

Ok, I 'll go with user error, I am new to this.

I carry point down, is it possible the bolt slides out a bit?

I will adjust the string, check all fasteners, and try some new bolts.

Also emailed Excalibur.

Thanks again!

I have a habit of always checking the arrow to see if it's fully seated when on my stand. I use my left thumb to push the arrow back.
It has never come foreward.

Yep it is possible for you to jar the bolt out a little...always check and make sure bolt is back all they way. I would carry bolt up if stalking other wise it is not cocked untill I get to my spot.

Got in on this late, but I noticed you said:

Did you, or someone else by chance grind off half moon nocks to make them flat? If so, I'd say they may not be perfectly square. If they had a slight angle in relation to the arrow, they might actually be making the string jump off.
If they are factory flat nocks, I'd check them for any possible damage.
The only time I ever had the string jump off the arrow (one time in hundreds of shots!) I had set the bow down with the arrow in place (stirrup down) and figured I'd jarred the arrow off the string.

wabi I think ya hit it right on the mark

Dennis take them plastic nocks out and replace with alum. inserts or flat alum inserts made for bolts and your problem will be gone.
