something strange

Well got to shoot some today, target was a box with some rug stuffed inside. Had something strange happen had one bolt that would not shoot was looking for it and was still in pistol under the string. After sever tries I put some fiberglass electrical tape and super glue on the string were the string comes in contact with the bolt. It worked after that.

That kind of misfire is usually caused by pulling the trigger too vigorously and not having the bolt in the right place. Those pistol bows have basically a push pin lock and if you pull the trigger too fast/hard it flips the string up too vigorously and if the bolt is too far back - the butt is a hair beyond the lip of the slot - then the string slips under the bolt instead of hitting it square.

It was only doing it with the one bolt, and the string was actually going over the top of the bolt.
The string was wearing a notch in it and the fiberglass tape and superglue solved that issue.
Yesterday I took a Vacation day so was a crossbow day, got some shooting in and did notice that the fiberglass tape had worn through from rubbing the rail, so flipped the string over, And I am using string wax.
I also added a small wooden shim under the prod to raise it to better line up with the rail to my liking.

I have had this happen as well and have found that I usually do not have the bolt seated correctly.

Had it happen to me again, the placement of the bolt did not seem to made any difference.

I JB welded a thick piece of plastic on the upper frame so there is no room for string to jump above bolt, so far so good.
