? why are my broadheads way off when i shoot, verses field points??

Hello all. i am new to bow hunting and shooting. i have my bow sighted perfect with my field points. 20 - 50yrds right on everytime. when i try my broad heads its not even close.. ones high ones left ones low, all about 8" to over a foot sometimes? not even consitant at all.. swith back to field points, all perfect. Im shooting a Bowtech Admiral set at 72lbs , carbon express arrows.. i am very confused.. please help. thank you..

 

Let me guess......Fixed blades?

Here's a suggestion.....

Tune your bow/arrows with the fixed heads on......THEN shoot your field points.

 

Your arrows are most likely not coming out of your bow perfectly straight.

When shooting field points this is not as big an issue, because the vanes straighten them out. But when you screw on the Broadheads and shoot them, the broadheads fight the vanes for control of the arrows flight. You need to adjust your rest so the arrow leaves your bow perfectly straight.

 

I'm sure some of the experts will tune in eventually...but my suggestions are to make sure your arrows match your set up. You have found your center shot, and your bow is properly tuned. If things aren't matched up...things don't work out right. Good luck!

 

Start with center shot.

If you know what that is (and how to set it)......next thing would be to make sure you're spined correctly.

What arrows are you shooting (spine)? What length? What weight tip?

 

Arrows are carbon express 6075 i cant find a weight anywhere on them. yes they are fixed heads 3 blade 100grain, the field points came with them for practice 100grain also. cant remember the name brand...
center shot? not sure what that means, can you please explain?
So it is bad that i set up my bow to the field points first? right now the sights are dead on...
thanks

 

No. It's not "bad". It's typical, actually.

What you're gonna find is.....those blades on the front of your arrow will act similarly to the vanes....and they'll try to steer your arrow. If your arrow isn't flying true from your bow, they'll (BH's) magnify your tuning errors.

The reason the errors don't show up in your FP tipped arrows is simple.....

Fletchings hide a lot of ugly.....lol.

Don't take that badly. You could be very close.

Send a PM to Bruce Lanthier. Whatever he tells you to do.....do it. Be willing to possibly crank your bow down a few #'s. too. Not definite....just be willing.

 

What you also may want to check, on top of doing all the advice already given is spin test your heads too. SInce you said they are going all over, your heads may not be spinning true.

 

So is it better to shoot mechanical heads. so it doesent affect the flight as much? this seems so complicated.. i thought it was all set when i was shooting the field points, i was stoked that i was getting small groups.. till i shot the fixed ofcourse.....

I started out at 20yrds to get the first sight, then walked back to 30, 40 50 etc. this is how i set my sights .
if i sight in my bow to the hunting heads, then i shoot my field points will the field points then be way off too?

 

by meaning heads not spinning true, do you mean they may be crooked in the shaft?
i can actually see the arrows turn in mid flight, i thought i was loosing my mind,,

 

Yeah, if you "sight in" your bow with your BH's then your FPs will be off. Thats why you have some tuning to do. The objective is to get your FPs and BHs hitting the same spot. Rest adjustments are necessary to achieve this.

 

I am sorry if i seem slow at understanding all this. But what has to be adjusted? it doesnt make sense to me probably cause i am so new to this.
what do i do split the difference in the sights? I live in Hawaii and there are no archery shops on my island, so local help is a no go..
I guess i have to decide what tips i want and start from there correct.
What is the most desired or recommended mechanical tip?

 

NO......OK...."maybe"....lol.

Seriously...."once your bow/arrow is tuned", it's a personal preference. It appears (drawing 70+#'s) you have sufficient energy to shoot mechanicals. BUT....never shoot them JUST to hide tuning flaws. Your arrow isn't flying true. The flight you're getting with fixed heads prove this (unless, like Rybo says, you're ONLY experiencing wobble, due to your inserts/heads not being square). Your fletchings are correcting your tuning errors (IMO).

If I were in your shoes.....I'd take my bow to a reputable shop....and tell them you need to check center shot. If they'll teach you as they check it.....all the better. Once you have that set....you can eliminate that as a contributor. Then....move to your arrow. Your arrow's spine will be your next thing to check. Spine has nothing to do with weight. They'll know (reputable shop) how to check this.....and advise you, further.

You have some options on how to manipulate correct spine. You could add/subtract tip weight; adjust draw weight; shorten your arrows (or add length, if new arrows are required).

You have LOTS of options. You just need someone with a little know-how.

Tuning any bow/arrow combo is a lot of "if"-"then". These are things you'll learn, the more you inquire.

Good luck!

 

is there i website or a article i can view that explains the proper set up ?

 

Jeff....go ahead and admit it. You MISS compounds. LOL :D

 

i wish i had a shop to go to, like mentioned above there is none on my island. a big bummer..
so would you say that my bow is tuned only to my field points?

 

ONLY if you're "close". If you're way off, that likely won't solve your problems.

I'll say it, again.......switching to mechanical heads, ONLY to solve a tuning issue....is NOT the way to go. You're STILL going to be robbing your setup of energy.

 

Download the Easton tuning guide. Its a good start.

I don't miss compounds in the least......lol.

What I DO covet....is the MANY additional tuning tools you guys have at your disposal (ex.- tuning via draw weight adjustments).

 

I was speaking in general....I'm sure he may have some rest tweaking to do.
