WW 150 gr. screwin breaking

[bolong]

I shot a hog this past Friday at 14 yards with my 48 lb. Crow Creek longbow. It was the first animal I had shot with the ww screwins. I did not get a passthrough and found mr arrow about 25 yards down the bloodtrail. I first thought the xx75 shaft had broken off but then saw that the insert was still in the shaft.


then I noticed that the ww hadbroken off in the insert. Just wondering if anyone else has had that happen.  It was a first for me and I,ve had lots of chances for it to happen in the last 41 years.

I am a little confused by your description.
It sounds to me like your adapter broke. Is this an adaptor that came with the head, or another aftermarket adaptor that you glued the head onto?

If you are talking about the new 150 gr. screw in elite's, I have had one do it in a foam BH target.

I believe those are "guaranteed for life" by 3 Rivers. Send it back and get a new one.

I had the same thing happen to me this year with my elk. Broadhead passed through into the far leg and was snapped off at the insert when the elk took a step. This was with a standard woodsman 150 screw on.

It was a standard woodsman 150 grain screwin. It broke off inside the insert about where the threads end.

The broadhead adaptor is the weakest link in most screw in broadheads.  That's where most breaks will happen.  Remember reading a while back that there was a problem with 75 grain steel adaptors breaking.  Apparently, there was very little steel right behind the collar and they tended to break right there.  Have since been redesigned, I've read.  Might be the same problem in whatever adaptors are used in the heads you're using.

3 rivers has new adapters with cross section photos on their site....


that problem was to fix the 'corner' or junction of the ferrule section to where it steps down to the insert section.   in the 75 grn adapters the hole milled in the center went too deep not leaving enough steel at that corner.

I think bolong is describing what dr ashby was finding were the shank part was smaller then the threaded part make the shank weaker and it would snap off just at the threads on angular hits or deflections.

The new 75 grain adapters are fantastic, but the 150 Original Woodsman bolong is describing uses a 25 grain aluminum adapter.  Sounds like it broke just like the 75's Ashby had though, there is a lot of stress at that point especially in a "shear" situation, such as being imbedded in offside bone when the animal flees.

Can't help you.  I'm 2 for 2 with the same head and pass-thrus.

Good luck the rest of the way.

Hey Bolong I think the broadhead stuck in the shoulder on the other side. Those hogs in AR. are tough. I say send it back for a new one.

[Tatersalad]

So did you kill the hog?  Don't keep us in suspense!

[Curtiss Cardinal]

Sounds like poor arrow tuning combined with metal fatigue. Steel adapters and brass adapters are superior to aluminum, the glue in aluminum adaters are better than  the screw in for strength.

[pseman]

Poor arrow tuning?? I wonder how you figured that out from his post?

[James Wrenn]

With any screw-in head you need to make sure it is screwed in tight.If it backs out a half turn something like you describe is more likely to happen on a hard glanceing hit.I have always used aluminum adapters and never had one break or bend unless it had screwed loose some.jmo

The arrow was tuned properly and flying true. I also had a lock washer on and I know the broadhead was tight. No, I did not recover the hog so I didn't get the point back. Right after I started trailing the hog it came about a 2 inch rain and washed away everything. It was in a 5 year old South Arkansas clearcut and visibiliy was about 2 feet, I looked for sveral hours after it quit raining but never fount him.
