Tuning Broadheads!!
 

Ok time to start shooting broadheads,, so my ?'s this, once you have spin tested your bh's, what's next??

do you shoot them and see how they fly? then try somemore adjusting?

once you get them to the best of thier ability,and they are still alittle off do you now begin to adjust your site for the final stage??

thought i would pick your brain to see howeverybody does it,, should probably take a poll on this one..

Check out the tuning manual. Very good info. First, even before spin testing, make sure the bow is tuned. Then, after spin testing, yes, shoot one and see how it flies. They may or may not hit with your field points, the group is what you are after.

Read through my link, it will get you started.

The keys to good broadhead flight include not only tuning your bow, but tuning your arrows. Spine should be adequately stiff. Borderline spine is not so good with broadheads. Spine testing your arrows is very beneficial if you can do it. Making sure you have adequate F.O.C. will help. I like to keep it over 10%. Putting a helical fletch on your arrows will help a lot also.

Combine all this with a well tuned bow and you'll have great flying broadheads.

I have found that lots of archers try to use too littel fletch on their arrows , shooting broadheads . I like 3 5inch feathers , or 4 4inch feathers for fixed broadheads . Trying to tune a big cutting fixed head with , say 3 3inch vanes is fustrating , and futile .

Straightarrow has given good advise , I see lots of archers shooting 29" 400 spine arrows at 70 pounds , way underspined

I personally shoot broadhead arrows and field point arrows at the same spot. If the broadheads are off, I adjust the rest and nocking point until both types of arrows hit the same exact spot. Bare shaft tuning would accomplish the same thing.

edit double post.

I just set up my new trophy taker and I got it to shoot field points and broadheads. I shoot a broadhead and field point into the same dot on the target. I have three dots and shoot three times (six arrows). Then I usually tweek the rest L to R to make them hit the same. Be sure you only move the rest a "hair" at a time. Good luck.

RE: Tuning Broadheads!!
 

After the bow is sighted in for field points I will proceed to shoot the exposed blade broadheads to see if there is a difference in the point of impact. If there is then I make the appropriate adjustments to my nockset height or arrow rest position. The Easton Tuning Guide linked above is what I typically follow. All have given some good advice though.

RE: Tuning Broadheads!!
 

Now a Question,
You paper tune and move your arrow restposition or nockset height to shoot bullet holes,
Now your going to move it again to adjust for broadhead flight, well you just screwed up your paper tuning. Am I correct? They both can't be right. Just wondering about this. It's like you can't have your cake and eat it too.

RE: Tuning Broadheads!!
 

Paper tuning is great if your shooting at foam. It gets you really close, but is a starting point for broadheads IMO.

;) foc target or 3d 7% for me.foc for bad to the bone muzzy 12%.

RE: Tuning Broadheads!!
 

FMARC, first and most important is to bare shaft tune your bow with the arrows you will be using to hunt tipped with target points matching the weight of your broadhead. If your arrows are matched to your draw weight and draw length your broadheads will fly and impact itentical to your field tips. Oh, another important tip, make very sure that your arrow are straight. A good practice is to set aside new arrows just for hunting and keep them just for the hunt. Use other for practice and 3-D shoots.

Wells, what you you rather do? Shoot perfect holes in paper or hit what you're aiming at? ;)

Ok guys just shot all 6 of my bh's 2 out of the 6 shot well.. the other 4 all shot 1-2in low. so what would u do??

1. adjust nock down?

2. get 4 good and 2 ?? then spin test the arrows

3. move sight down??

let me hear it !!!!

RE: Tuning Broadheads!!
 

Check f.o.c first.Then check how broadhead lines up with fletching.

RE: Tuning Broadheads!!
 

MY F.O.C is 8.3 i thought lining up your fletchings had zero impact on flight??? cr@# now im going to have to find that link huh...

RE: Tuning Broadheads!!
 

Forget about the lining up with fletchings thing. It's a bunch of bunk.

I suspect that the four that fly not so good do not spin perfect. I bet there is just a bit of wobble to them or the blades may be slightly bent if you have shot them a number of times..

If they all spin perfect and the blades are straight then the next step would be to move your nocking point down in very very small incraments. I'm not a believer in the thought of not having your broadheads and field points impacting the same spot and simply moving your sight.

8.3% is pretty low IMO for a hunting shaft. You may want to fletch with feathers to get the rear of the arrow lighter to increase the FOC or seriously consider a heavier broadhead as long as it won't make the spine of the arrow to weak.

You might want to post your bow, draw length, draw weight, arrow length, which arrow you are shooting, the arrows spine #, and broadhead weight.

Bigbulls,

the flight of the arrows is great!!! just hit alittle low. some could be just spinning them,but for the most part they are pretty smooth.. i did the FOC CALULATOR SO THATS WHAT IT GAVE ME,, 70# 28in vapor 4000 @ 29 1/4 100grn buzzcuts

RE: Tuning Broadheads!!
 

Sounds like you may need to lower your nock point or raise your rest slightly , 1/32-1/16 of an inch .

RE: Tuning Broadheads!!
 

JIMMY

that was my next ? .. does it matter which one i do?? is one preferred over another?? raising the rest or lowering the nock??? moving thr rest would be much easier for me..

RE: Tuning Broadheads!!
 

I would do which ever one brings the center of your arrow closer to the center of the hole in the risor that mounts your rest .
