Bolt dropping 4 feet ????

When I shot a bolt from my Tenpoint it dropped 4 feet from where I was aiming at 30 yds. All other bolts ok and hit the point of air. I noticed the plastic fletching where it rides the groove in the rail was wavy. Could this be the problem ? The bow also made a funny sound . I changed the flat nock and still dropped 4 ft. Like I said all the other bolts flew true. Any ideas what caused this to happen ?

If all other arrows fly true. the one that does not is defective in some way.....use it to de-cock after a day's hunt.

Re: Bolt dropping 4 feet ????

if you are using carbon bolts, CHECK IT FOR CRACKS. that could be making the funny noise. if its cracked it could bow apart and you could get injured.

that wavy fletching could be causing the same noise issue and the drop. it could be catching excessive air when shot.

get it refletched and inspected, then see.

Re: Bolt dropping 4 feet ????

Two things to check that I had with my Tenpoint. Both will cause you to shoot low.

1 - Check to make sure the bow part did not loosen up from the barrel. Easy to check. Grab each limb side and it will wiggle back and forth if it did. Easy fix - tighten the bolt on the end.

2 - Check your trigger mechanism to see if loosened up from the barrel. You can do this by grabbing it on the top by the scope and see if there is some play in it and it lifts up from the barrel in front. There are two screws that connect it to the barrel but you need to take the barrel off the stock and then you will see where they are to tighten them up. After this happened to me the second time I added a little Loctite before putting it back together. What happens here is when you shoot, the trigger mechanism lifts up a bit and the string goes high on the bolt pushing it down against the barrel. This will cause the fletch issue you see and in my case even made some wear marks on the barrel where the bolt drug.

Let us know if you find either one to be your issue.

I would not shoot that arrow again. If the other arrows are flying true, discard it and use the rest. Not worth tinkering with it as something is way off. A bad vane would not cause that much poi difference at 30.

Re: Bolt dropping 4 feet ????

thanks to all. The bolt is now in 2 pieces in the trash. I checked the bow out and couldn't find any cracks etc. I shot another bolt through it and it worked fine. Must have been a factory defect of some kind. Would have been much worse if I were shooting at a 150+ buck and it shot that low. lol. Glad
I tried it out before hitting the woods.

I shoot every arrow before they go into my quiver. There is usually one or two that just won't group with the others.
