Sitting here pondering broadheads as I prepare for spring turkey season. Field points on my full length 75-80 wood arrows are 160 grains. I have 155 grain Grizzly broadheads on them and they fly pretty well. That being said I can't help but wonder if a true 160 grain head like a Cutthroat would fly better or closer to my field points. I shoot broadheads year round. Really though, is it splitting hairs when shooting wood arrows anyway? Is 155 close enough to 160.

Weigh ALL your arrows and all your heads by themselves and I think you'll find 3-5 grains difference already between them.
I certainly can't tell a difference of 5 grains. 25...maybe. 50 grains yes, but usually only past 20 yards. Then it's a little more drop.
-
little or none.
HH~

That's where I am at with it. I notice subtle changes from arrow to arrow but there is more variation on shot inconsistencies than a few grains can ever make.
-
could be just a slight B/H change will bring them in...5 grains aint much but neither is a half twist in the string. :dunno:
-
Yeah, and now I am getting weird flight. They are dropping nock down and right in flight. and I occasionally get some cork screw. Not worried about grains now, need to adjust nock height again and may throw on some 190s and see what happens.
-
5 grains shouldn't be a problem at all unless you are borderline spine.
-
Nada. Up to 15 yards I can't see a difference between 145 and 200 gr. field points. But put on a broadhead, and things go south fast. My guess is your overall tuning is borderline, and changing the field point to a broadhead is letting the broadhead compete with your feathers on what end is controlling the flight. I stuggled with this, and my fix was to bareshaft tune with both a field point and a broadhead- when both are flying pretty good, it is time to add feathers and go hunting.

That's my concern. I am going to get a spine up and a spine down and try them as well. I have a new bow coming in June so can use everything to tune that as well.

As Blacktail noted, your broadheads might already vary by more than 5 grains. Depending on how you sharpen them, there may be as much as 10-15 grains difference in weight between your heads, and they're likely less than 155 grains. Too, unless you're weighing your arrows to within a few grains, they can vary by a lot more than the 10 grains plus or minus that the vendors say they group them in. In short, your arrows might have a physical weight range approaching 50 grains, and only a little bit of that is likely due to variation in broadhead weight.
Unless you have a good grain scale and weigh the arrows, or better yet, the individual components, you won't really know what may be causing the less than perfect flight with your broadheads.
One thing I do to try to arrive at equal physical weight arrows is weigh each individual point and shaft and put the heavier heads on the lighter shafts and vice versa. That can reduce a physical weight range of 20 or more grains to almost no difference.
Regardless, if your broadheads are only 5 grains lighter than your field points, and if your arrows are closely matched in physical weight and spine, you simply will not notice the 5 grains difference.
Be sure your broadheads are mounted perfectly straight. Broadheads that aren't mounted perfectly straight contribute to a lot more erratic flight than a minuscule difference in weight.

You are picking fly poop out of pepper.
Five grains is nothing. Your tips likely vary by that much. You have other issues.
If you think that five grains is causing an issue then get away from woods. Wood arrows will fly well with weight variation of 40 grains so long as the spine variation is tight.
For the life of me, I don't understand why you will buy a dozen shafts knowing that they will vary from 55#-60# (and you don't even know how many of each) and then expect consistent and uniform arrow flight.

I don't expect that consistency out of woods and was simply posing the question out of curiosity so no need to get your bow strings in a bunch. My tips and shafts vary that much. I am more curious about the responses. Carbon shooters fret over a grain despite tolerances and I am seeing that if I do my part my 190 and 160 tips are hitting the same, albeit with different drop, speed, and penetration. Form is more of a factor than than anything we all worry about materially.

This thread will not be deleted as it may help others with the same question. :campfire:

I usually get close with aluminum and convert to wood, or start close with wood and start trimming. I use broadheads to tune. 5 GR won’t make a difference. The more center cut the bow will also reduce how finicky the bow is to arrow spines. But like a Hill style bow usually you’re talking around 3 LB variance for better consistency. Just have to tinker
-
You should be fine. My woods vary as much as 10 grains and I shoot better than my friend with carbon. Fling on brother. Good question though. I find that my mindset with wood is different than some that shoot carbon. I like the feel and sound of wood. I'll deal with the variation.
-
I agree that, unless you are on the very edge of being out of tune, 5 grains won't make a noticeable difference.
-
I don't think you will be able to tell, if you don't mark it as different when you put it in the quiver it is unlikely you will ever be able to pick out which one it is.

There are 7000 grains in a pound.
don't sweat the small stuff and 5 grains is really small stuff.

Just my personal experience, but I find the type of head I'm shooting has more effect than a few grains difference. In other words, a field point, broached, and judo may all fly a little different at the same weight. For some reason I can't really figure out, my 135grn judo's always seem to shoot better than same weight BH's, or field points. So, I just adjust point weight as necessary for best flight... might go up or down some to get 'em where I like 'em.
-
When my bow is tuned, I can shoot anything off the front end within 50 grains and hit the mark.....Judos, Condors, Hex, 2, 3, 4 blades.
-
I shoot wood arrows with a variety of heads and weights. Unless a broadhead is misaligned they all shoot good. Heavier points I don’t notice a difference until I get out to 30-40 yards or more.
