Field Tips vs Broadheads
 

I got a Block target today and decided to see how close my Montec G5's hit to the same weight field points. They shoot about 6" left and a couple inches low at 20 yards. Based on the information in the Eastman tuning guide, I tried adjusting the rest to bring the two together. No dice. When I get the broadheads hitting on the target, the field points shoot to the right and a little high. I have (or had) the bow tuned really well for the field points - great groups - paper test perfect, center shot perfect, walk back perfect. I'm thinking the "easy button" here is to just move the sight to adjust for the broadhead impact. By measuring the distance to the stops on the sight with a micrometer, I could find my previous setting pretty easily. I looks like, for this setup, moving the sight .025 results in 1" of impact shift at 20 yards. Anyonehave a different view onthe logic of this?

How is yourarrow spine.

Also,do you have hand torque causing a kick in the arrow?

RE: Field Tips vs Broad heads
 

I would say move the sight if it was tuned great and shooting the field points great . I thunk moving the rest will put it out of tune. you are getting the results of another post here that was shot from a machine and a lot of broad heads shot left and low of the field point

The spine is right on the money, according to Easton's charts. ST Excel 500 at 28" with a 100 gr. point. Best of all, the arrows will group 1" at 20 yards and are tearing paper just fine. Walk back is good out to 55 yards - the furthest we can shoot at our range.

I see what you mean, though. Grouping the broadheads to theleft of the field pointswouldpossibly indicate too stiff of an arrow - or the draw weight is a little low. And moving the rest, once the sight is readjusted, doesn't seem to help. Now that I think about it, yesterday when I was shooting the bow at different draw weights, the same arrows with the same field points hit 6" left and a little high with the draw weight set at 60 lbs. Didn't group as good as they did at 51 lbs., though. Should I maybe try 125 gr. broadheads?

This is why I'm a firm believer in practicing with what you hunt with, broadheads.;)

RE: Field Tips vs Broadheads
 

This is why I paper tune bare shafts to check spine before anything else.Then check fletched arrows for contact through paper.




If you read my post on this subject,you will see my whole process and whenI am done,mine hit the same.

RE: Field Tips vs Broadheads
 

Are your arrows tuned? What I mean is, when you screw on your broadheads, spin the arrow. Does the BH wobble? If so, you'll need to do some work there.

Also, I noticed you are shooting 500's @ 28"....At what poundage?

RE: Field Tips vs Broadheads
 

Very good point,the broadheads must spin true to fly true.


Broadhead flight is why one should never use cheap carbons and should also use helical feathers IMO.

RE: Field Tips vs Broadheads
 

you don't deer hunt with field points so who cares how they shoot. sight it in with your broad heads you should practice with those any way. and montec makes practice bh's for that reason

RE: Field Tips vs Broadheads
 

Had a similar problem with a friends set up, he was shooting wasp boss bullets 75 grain, flight with field points and broadheads were great just didnt group together.Spine was good bow was tunned no torque, but he did end up changing fletches and it tightened them right up.

RE: Field Tips vs Broadheads
 

Broadheads don't wobble and they group pretty well. Pull weight is set at 51 lbs. I have a notion to increase the pull weight and see if the two points of impact don't come closer together. Or maybe see if a 125 gr. broadhead will shoot closer to the same spot as the 100 field point.

RE: Field Tips vs Broadheads
 

This is true, but you're losing penetration and performance if your bow isn't tuned properly. Your bow should be tuned regardless of what tips you are shooting.

RE: Field Tips vs Broadheads
 

It sounds to me like you may have a combination of problems. I would go through tuning from square 1.
The other questions I wonder about are:

Are u using helical fletching? Are u lining up the vanes w/ the blades of your bh?
Are the arrow straight? It seems to me the straightness tolerance on Excel's is .600. That's not the straightest.
Do you have rest contact? Do a powder test.
If your walk back tuning is o.k. and you have some minor contact,it won't show up in fp's but will in bh's.
Montec's are not as accurate as some other bh's. Did u see the video in yesterday's post here?

RE: Field Tips vs Broadheads
 

Sure did. The video showed the Montec G-5 hitting low and left from the field point in what I assume to be a "perfect" bow. I just hate to start trying to "tune" a bow that, so far as field points are concerned, is dialed in.

RE: Field Tips vs Broadheads
 

Something about your setup is out of tune.........fieldtips will cover this up but fixed blade heads will always show it. How do your arrows fly?? They can't both be flying flat and true and hitting so far off. One (or both) of them has to have less then perfect flight.

There are so many variables here that the best thing to do would be to start from scratch (thankfully it's not hunting season) and figure out what the problem is. Could be arrow spine, FOC, torque, form, rest contact, inserts, BH's, nocks, flecthing, draw weight, draw length, sight, peep, etc.

Lots of stuff that it could be.........most likely it is something simple. If you are not familiar with tuning your bow go to your shop and tell them your problem and have them figure it out (that what they are there for).

Don't let anyone convince you to move your sight THAT much..........if it was only bumping the sight a little bit (1 inch) then fine but being off by as much as you are is a definite sign of a problem.

Good luck..............and as has been mentioned already this is EXACTLY why I encourage everyone to practice with broadheads as much as possible. Imagine how you would feel if opening day was this weekend??

RE: Field Tips vs Broadheads
 

My BH and FP do not have the same point of impact,yet both group well w/ each other. We've tried tuning the bow but no luck. My buddy who helps me with this has an older bow that is just like mine, his switchback however shoots them both the same. Some older bows just won't have the same Point of impact when shooting BH and FP. I sight in my BH and practice w/ them for a month before hunting season. All summer I use the FP,way easier on the targets!

RE: Field Tips vs Broadheads
 

Paper tune after the initial setup. I'll say it again, paper tune after your initial setup. I use Montec 100 and 125 gr for huntingand same arrows with 100 and 125 gr field points for practicing. The Montec's will fly to the exact same spot at the field points as long as the bow is in tune. If it's not in tune they won't hit the spot. Not just Montec's, but any fixed blade
head. You can be way out of tune and get damn good groups with field points and believe that you've got a great shooting bow. People do it for years and never have any idea that their bow has never really been in tune. Bear shafts will fly the same too, as long as the bow is in tune. If you don't know how, have your bow shop help you, or go to one that does know and will help. You won't be sorry.

RE: Field Tips vs Broadheads
 

I am lucky that my field points hit within minute space from broadheads. My thought is your bow, like some guns, handles one shell better, mine handles one type of broadhead. I use Crimson Talons and hit where the field points hit, yet I used another type from Spintite and it did the same, like right and low. So I switched back to the Talons and was on again. So think you might want to try another broadhead!
