Thunderheads at high speeds
 

I've heard in the past that once you got up over 285 fps with thunderheads you will have troubles controlling them. Is this true?

My old setups have never been an issue, but I've never shot over 265 fps. My new bow is significantly faster, probably in that 280-290 range and I was wondering if I am going to run into any issues, or if I just have to try it and see.

I'm going to use some thunderheads for turkeys and i wanted to see how they shot out of my 101 and they were dead on. My bow is shooting around 300 fps so you should be ok if your bow is tuned.

I've shot them at 292. Who knows how some have problems, or if there ever was.

Properly spined arrows, adequate FOC, and proper fletching you will have No problems shooting Thunderheads at those speeds.

I shoot the 100's on my back up bow at 290. There's no problem at all.
If your bow is only slightly out of tune , it will show up at those speeds though. A big head like a TH will magnify a problem.
They make a great tuning tool. LOL!!!

I never had good luck with them anyway so I quit using them and went to Muzzy 4 blade. Hit my mark every time.

IMHO, the issue that so many people have with thunderheads as opposed to other fixed blade heads of similar size/design is the o-ring that comes with them. When you screw them down, the o-ring does not always stay where it is supposed to, and can be compressed right out of the side of the head/insert interface. This can lead to alignment problems.

If your heads are spin tested, and spin true, they will perform just like any other head with a similar design.

I went on this crusade to get another broadhead. I got tired of the blades coming out on thunderheads. I tried mech's, tried montecs, and others, but I went back to thunderheads. I shoot 280fps out of my commander. They shoot just as well as others.

I had some problems with them and changed to SlickTricks 100 mag.

What was the problem?

RE: Thunderheads at high speeds
 

Glad to see.
I certainly have confidence in tuning my bow, have NEVER had any issue with T-heads, I feel they are one of the best heads ever made. I'll tune em up and be ready to hunt.

I shoot 307 fps using Maxima Hunter 350's and the Thunderhead finds the right spot time after time.

thunderheads do seem to be one used for alot of tuning purposes, I am around 180fps and shoots fine. had to have my bow tuned up really good to do it though it took a little while.

85gr Thunderhead @ probably 305 gets the job done for me.

The deer seem to have a problem with this combination.

RE: Thunderheads at high speeds
 

I did have some issues with them in the past, and getting them to fly straight, but they were also older heads, probably 1999-2000 circa, so they may not have been as good quality as what you can get today, but I've gotten Muzzy's to fly pretty well that were older, and I've heard guys have issues with newer Muzzy's saying they were lower quality than older ones. I think maybe there's an occasional bad batch or something!?!? I only am shooting mid-270's though, so I can't say at "HIGH" speeds what the performance of ANYTHING would be.

RE: Thunderheads at high speeds
 

I have use the old thunderheads for years, have many left, plan to shoot them for many more years and they shoot very well, but I shoot 242 FPS with 125grs.

However they pass through the rib cage and stick in the ground. See no reason to change.

I am pushing over 300 with my 101st and I put my TH 100's on for turkey hunting so I can shoot through the netting and they fly awesome!! Walt
