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.
