Thunder Heads?
 

I am shooting thunderhead 100gr and a 60 pound draw, I go to shoot my bow and the arrow takes a path of its own. Its crazy I have never had that happen but any suggestions? I am shooting 20 yards away and my shots are way off, I can see the arrow curve left in the air.

Start over. Take it to the shop and have them check it out. Something either moved, stretched or broke.
That is assuming you have shot this setup before. Meaning same poundage, arrows, etc...

This is a new bow, I went to Cabellas and they over tightened my draw weight and broke the mount to the limb. Its the same model and I had this set up last year, it must be the broadheads because I just shot the field tips and it was fine?????

Could be an alignment problem with the BH. Spin the arrow with the BH mounted and make sure it spins perfectly.

Ya it spins perfect in my hands. Could it just be the type of broadhead itself.

It ain't the broadheads, Thunderheads are some of the finest heads ever made...Something has changed about your bow setup...It could be several things...

Double check the draw weight and make sure the arrows are spined correctly...Did they increase the draw weight when the bow was fixed???Has the tiller changed???

After this, go back and make sure your rest and nock are in the same position...If you don't know how, take it to a pro shop and have them start from the beginning...

Tiller? Sorry kinda new at this. I took the broadhead off and put a fied tip and it shot fine. The draw weight is the same and the knock and rest align perfectly.

That's what I'm trying to tell you, you have to adjust the nock and rest to the broadhead so they hit to the same poi as the field points...

Initial setup is like bore sighting a rifle, you still have to adjust to the ammo being used...

Well said.... and X2 on nchawkeye's assessment of Thunderheads. :happy0001:

Dan

Its probably exactly what nchawkeye said. Your rest and nock probably need to be tweaked some until both the field points and broadheads are hitting the same spot. Ive shot Thunderheads for a looong time and its not the broadheads. My suggestion is take it to a local pro shop and have them check it.

Awesome thanks guys that my goal for today.

There is nothing wrong with Thunderheads, I used them for years. I consider my bow tuned and ready for hunting when I can hit an apple at sixty yards, and I did that many times when I was shooting Thunderheads.

I love thunderheads, but never found them to be the most accurate head. A person that is new to shooting or torques the bow, thunderheads will show this. Or of course if bow is out of tune. Like others said, BH tune the bow.

Only thing I never liked about thunderheads is they are weak. I rarely get to use em twice on a deer unless it was a quick thru the lungs shot, and have had many deer actually break them at the shank by rolling over the arrow or hitting the knuckle of the shoulder at an angle. But one thing they are is about the sharpest BH's out there.

Mark, that's another reason I USED to use them. I went to Muzzy Phantom 220 grain because they are .040 thick and cut on contact. I'll stick them them as long as they continue to make them.

I heard rumors they might quit. So I bought up a few sets this winter. I love the 200gr phantoms. I never use the bleeder. Probably the toughest head out. Or steelforce. But never was a steelforce fan.

I talked to a shop and they suggested I try and shoot montec, Ill adjust my bow to the thunderheads for now. Its just crazy they shoot 6" low and left compared to the field points. I can see them curve in the air.

I shoot 100 gr. Thunderheads...never had an issue...I usually have to adjust my sight a little bit to them...they don't fly exactly like field points, for me anyway, but when it comes to putting down a deer, they work well!

So I got new arrows and sure enough they fly perfect. Thanks guys.

Thunderheads can be bad and or poorly installed, not likely on the bad part. What they do is magnify problems. If your shooting one arrow it should be doing the same thing everytime, if it is try a different arrow and see what happens. If it's going all over the place you probably have a mechanical problem but the main one is you, your not shooting the same everytime.

Great improvements in your setup can be accomplished if your willing to do the homework and put in the time (ain't happening with this thread), or you can shot a mechanical head and live with it for now.

The T-head is talking, could be one problem, could be many. Books have been written in an effort to answer them. I like this site although it's not a broadhead site. There's a lot of others.

I hope not, I just bought some more myself. I'll stock up to last me the rest of my life!!!

Heck I'm 60 how much longer am I going to last..:guiness:, the darn broad heads will probably outlast me.:)

So the arrows were spined wrong???

Ya must have been? With the field points they shot fine but with the broadheads they didnt. The shop suggested new arrows with shorter fletchings and they shoot perfect.

I shot thunderhead 85 grain a couple years ago. they just really well except for left and right. if i shot my field point it would be dead on, when shot the thunderheads it would hit about 8 inches exactly left, so i just sited my bow in with the broadheads and eventually switched to RAGE!

I had the same problems when sighting in my BHs, they were hitting low and to the left from where my field points hit. After fiddling around with paper tuning, adjusting the rest, knock point and sights, the answer came when I changed arrows to a stiffer spine and better quality arrow. Now my BH and field points fly together.

Stay away from the Walmart specials, even their most expensive arrows are a piece of junk. Guess you get what you pay for. Now I'm shooting Carbon Express Maxima Hunters, 350s for a 67 pound bow.

I won't be changing arrows any time soon as I recount the numereous hours wasted trying to tune around bad arrows.

Funny. I've had more problems with Thunderheads thana any other broad head out there. All problems were due to the the shaft (threaded part) of the head being bent. Had to run several of them through a head jig to correct them. Decent head, but their quality control department sucks.

correct one issue at a time. Left issue can be corrected by incremental adjustmenst RIGHT with your rest. The low shot just may be the way the head flies, I have a slightly low hit at range as well, otherwise, move your rest down a touch.

Unfortately I found this to be case in the past few years also. I would have have to cherry pick arrows and find good combos. I always thought it was the arrow not the head. But if I put a montec or slick, or phantom on them, wouldn't have a problem.
I think its more that oring.

I thought that was the case as well, until I switched the arrows and bought Montec heads. Tried them both with new arrows and $88 later my problem was fixed. Its really a hit or miss with thunderheads I think. If you have a good combo they kick A$$.

You need to tune your bow, arrow, and spin test your broad heads. I used thunderheads for about 10 years. They are a fine head, like most all. But like all, you need to have tuned equipment.

I have noticed with thunderheads, not as many tune as well as others. That is one of the reasons I switched. I got sick of constantly messing with the blades to get them to spin right.
