BROADHEAD VS FIELD POINTS

SCOPE · Jul 27, 2004

QUESTION, I'M HAVEING PROBLEMS WITH MY 125 GRAIN BROADHEAD SHOOTING 8 INCHES LOWER THAN THE FIELD POINTS. I'D TRIED PUTTING ON AN 100 GRAIN BROADHEAD FOR THE HECK OF IT, AND FLEW EXACTLY LIKE THE 125 FIELD TIPS. NEED A LITTLE HELP.

Way more head out there to catch the wind. So there for it drops a bit faster than the feildpoint.
I always shoot a 125 grain field tip if I am going to use a 100 or 85gr broadhead, just makes it so ya dont need to do near as much tinkering.
regardless of how well your bow is paper tuned and timed, fixed heads will most the time hit diff then fieldpoints.
I am currently exp with the 85 gr thunder head the 100 gr thunderhead the 100 gr cross fire the 125 splitfire the 75 gr inerlock and the new phantom from muzzy.
I will not shoot the splitfire or 75 gr innerlock for my hunting needs just testing them, I have been exp with the inner locks and the 85 gr thunder heads out of my bow and my wife's bow.
so far the crossfire and the 85 grain TH shoot best past 60 yrds the crossfire is built more durable then the TH.
the new phantom is a awesome well built head but I cannot get good flight past 60 yrds.

I don't believe it has anything to do with catching the wind, but more likely it's an issue with dynamic spine.

Broadheads are much longer than field points and move the weight further out. This effectively weakens your spine. In some boarderline instances it will cause grip torque and nocking point issue to surface rather severely.

I would try paper tuning with your broadhead to see if you have a nock high tear vs. very little with the field point.

Here's a few things that can be done to fix the problem quite easily.

1. Decrease bow weight 1 - 4 lbs and see how close the field points group with the bh's.

2. Add nock end weight. 4.125" or 5" vanes rather than standard 3.75" vanes or possibly redline unibushings and easton G-nocks. It's not the stearing effect you are after but a heavier arrow at the nock end which will dynamically stiffen the spine.

3. Double check your nock height via paper tuning to see if you can clean it up a tad. Some times 1/64" at the nock can make a huge difference in arrow flight off the rest.

4. Make sure your drop away rest is staying up long enough. Particularly if you are on the weak side with your arrow spine.
