Easton Injexion Arrow Build - Adding Weight Behind Insert?

[el_jefe_pescado]

I was gifted a mess of 330 spine Easton Injexions that came pre-cut and glued with standard D6 HIT inserts. I am trying to think of some creative ways to add weight and durability to this setup. Some quick stats below:

• They currently cut at 26.5 CTC (which is about as short as I can go)
• Bare Shaft + Insert is coming in at 310 gr
• I have a bunch of 125 grain Iron Will S in D6 that I plan to use with these arrows
• I am guessing with nock, fletching, wrap I will be around 460s TAW

I know this setup will work as is but am curious if anyone has ideas for getting adding another 20-40 grains to this setup. Any insights would be appreciated.

You could add the stainless iron will collars to add 25 grains?

 

[el_jefe_pescado]

Yeah, that's was my first thought but it doesn't appear that they make them for .165 ID? Unless, I am just not seeing them on the website.

Or is it that their size chart is referencing ID of the collar?

 

[JRB7]

They should have an option that works, it looks like it would be an “E” but their size chart doesn’t format correctly for my phone screen. The collars are sized off of the OD of the shaft. Here’s the link to the size chart

An external collar would be the easiest method. HIT inserts don’t have rear-facing threads, and thus can’t accept weight screws behind the insert. An Iron Will size E impact collar (available in 10/25 gr) or an Ethics .245” universal footer (available in 15/25/45 gr) should work with a 330 spine Easton Injexion.

Perfect. This is exactly what I am looking for. Thanks fellas.

Food for thought - I would use a lighter collar in Titanium and use a 150 deep six if you really feel like it. Honestly though, the best version of the IW head in my opinion is the 100 grain solid. Just my 2 cents, it has less blade surface area. That 50 grains isn't going to make or break a pass through. I'd take the little gain in speed.

There's some promo's out there for Podium Archer and you'd need size E https://www.podiumarcher.com/products/podium-titanium-collar?variant=43831409737903

You can add a 150Gr broadhead as well.

I shoot that shaft but cut longer carbon to carbon. I glue in the D-6 stainless steel insert at stock depth. It’s there for reinforcing and does a good job of it. I’ve used Firenock outserts with the standard threads for 8-32 broadheads over the shaft. With 3 vanes and a 4” wrap and 100 gr broadhead my arrows weigh about 470 gr. Killled several tons of critters with them the past dozen years. Tough shaft and penetrates deep…elk, bears including brown and polar, moose plus caribou, black bears, musk ox etc. Mostly with a 65# and 29-3/8”’draw Prime Rival. Arrows fly about 271 fps.

I used to shoot those arrows and I epoxied extra hits in and used the iron will collars. In fact, I think i have a dozen collars in my garage somewhere I could sell if interested.

Ive tapped the back of D6 inserts (i think 6-32) and added .166 gold tip weights to the back.
Lately I have been opting more for speed- ive been leaving the extra weights off my arrow builds-just using he insert+broadhead.

I think a 120 grain point on a 20-40 grain insert is more than enough to blow through something! Especially if you're flingin some speed.

Stock Easton D-6 inserts are threaded 6-40 (weak due to minimal cross section area of the broadhead shank). Regular inserts are threaded 8-32.

When I shot injexions I had the collars on them; does help with durability.

Did you find some? I may have a handful I will give you free if you want? Let me know-

I can't remember in that case do the gold tip weights just thread in freely? No tapping required? I know i tapped something in the past but maybe im confusing things

 

[Blockcaver]

Not sure on the Gold Tip weights threading, but if D-6 it should be compatible.

 

[The Fat Coyote]

Gold tip .166 weights are also 6-40, should plug right into the back of an easton Deep 6!

Deep 6 HITs aren’t threaded all the way through; there are no threads on the back side to screw a weight into. It would be theoretically possible (as you suggested previously) to cut threads into the back side of a D6 HIT, but they don’t come that way. I’ve cut rear facing threads into a standard 8-32 HIT, but it was a delicate procedure and I ruined several HITs in the process. I think tapping a D6 HIT would be even more difficult due to its smaller size.

Im sorry man im giving out some poop intel. I really need to revisit the inserts i have when i get home and ill post up some photos of what i did!
