Head weight

[nhbuck1]

My bow is tuned for 200 grain head with standard insert, what can I do to make the same weight with 170 grain zwiky delta? They would be stiff but actually fly good if mounted right, what are my options? I don't know how much a standard easton carbon insert weighs.

buy a book, goggle no easy answers here

several suppliers sell different weight bh adapters. I would replace adapter with one that gets you the closest to your desired weight...you could also add a footing to your arrows to accomplish the same thing.

[nhbuck1]

Even for screw in carbon heads with arrow inserts?

[Mike Faith]

Yes, I have ordered them from 3 rivers, I believe they have 75,100,125 grain. Just heat the head and hot melt the new adapter in the head. Use an alcohol burner, a torch can overheat the head and affect temper.

[nhbuck1]

How do you know what adapter to use to equal that weight? Won't a heavier brass insert work?

[Mike Faith]

Sure, it looks to me like the zwickey head has a 35 grain adapter because the glue on version is 35 grains lighter than the screw in, so you could use a 75 grain adapter in place of the stock one, or you could use a brass insert to achieve the desired weight, depending on what your inserts are glued in with may determine which would be easier...

I'm shooting the 3 rivers trade only arrows made by east on,I can't find what the stock insert weight is anyone know?

[nhbuck1]

Now the delta head advertises 170 grains is that with adapter too?

[Mike Faith]

yes 170 gr with the screw in adapter, trad only inserts are 11gr for 600 spine, 14 gr for all others...

[nhbuck1]

So a 50 grain brass insert would work? Where did you find the insert weight out from? Thanks mike

[Mike Faith]

Yes, a 50 grain brass insert would put at 220 grains up front. The 3 rivers catalog lists all the insert weights with the arrows they sell, and you're most welcome.

you can even do a bit of filing on the back of the insert if you are really anal about weight. I doubt 20 grains would matter much at distances of 30 yards and in.

I shoot a woodsman 200gr with a 50gr brass insert out of my Whip Classic 66" 45#@28 with GT Trads cut at 29-5/8 to the deepest part of the nock. they fly like lazers out to 22 yards. I shoot to much (60 arrows a day) I'm going to take a break for a month now and not shoot...
