Adding weight inside ferrules

[jsirm20]

Hello all, Im new here, I havent been shooting for 10 years and Im new to carbon arrows and all the adapters. It appears that the brass glue on adapters (glue in to shaft for glue on broadhead) from 75 to 125 grain have the same external dimensions. Is this true???

If so, What can you tell me about adding weight to the broadheads ferrule ahead of the adapter. I have the idea of gluing in .177, or 22 caliber  bullets ahead of the adapter, but my bullets and measuring tools are 1000 miles away now. What can  be glued there? I hope to use ACE or STOS broadheads

thanks

There are many ways to do it. Ive read some just melt some lead split shot into the broadhead ect...ect...

It might be much simpler to use a heaver broadhead to get the weight you are after, there are a hole lot of options out there.

I find the screw in system much more versatile.You can change from broadhead to field point to blunt.

You can get inserts,depending on shaft,14 grs,50 grs,100 grs.

You can then use adapters that weigh 14 grs,50 grs or 100 grs.Then,choose your broadhead weight.

I would forget bullets.It's much easier to adjust weight by adding lead shot,#6 or smaller.#6= app. 2 grs per pellet.

If you need to,you can drop lead pellets inside a 100 gr steel adapter.100 gr adapters vary but you can get maybe 18 grs of pellets in one or tamp them in,and you can get about 18 grs.

I can tamp about 20 grs of lead up in the ferrule of of a Grizzly broadhead,ahead of a 100 gr adapter.

Now,if you really need weight and have to use all available space in the adapter and broadhead ferrule,get some tungsten putty,as used for fishing weights etc..I tried to find what that stuff weighed and most advertisements were BS.The stuff I bought is 1.1 times heavier than lead.It is expensive at $5-$8 an ounce but real easy to work with.

You can lay all your components on a grain scale and pick off the exact amount of tungsten putty you need.You can pack it into the cavity of a 100 gr adapter,up in the broadhead ferrule or both.You can also re-use it if you change things later.It's pretty cool stuff.Oh,and epoxying the adapter to the ferrule adds app. 2 grs.

Using the screw in inserts and adapters plus whatever glue on broadhead you like,will give you an infinite variety of weights,light to super heavy and yes,I've played around with this a little.

I'm not a carbon guy, so am not familiar with diameters of carbon shafts.  But for my 2216 aluminums, I take over-the counter slingshot ammo, figure out the weight I need, and wrap it in aluminum tape (for ductwork).  My inserts are threaded on the back end, so I take a screw that fits and stick it in to the right depth so not to hinder screwing in the head.  I then wrap some aluminum tape around my weight and the head of that screw; this way, I can remove the whole get-up as needed.  I heat it up and goo on some hot-melt, and away I go.  (The aluminum tape can take the heat.)

Advantages:  Cheap, relatively easy, and completely reversible.  My judos can be 250 grains now.

Disadvantages:  For different heads, I may need to change the insert weight.  I also can't see how much weight is inside; need to weigh or remove and look.  Also, if there's not a good fit or enough hot-melt, the insert weights can rattle inside the shaft.  In the context of carbon, some changes may be necessary.
