Vented vs. Non-Vented

[ALDO]

Over the last few years I have been shooting Razorcaps.  Good flight and good bloodtrails.  I have a couple of the VPA non vented heads I am playing with.  I like the fact they fly quiet, as I always had a whistle with Razorcaps, Snuffers and even the Woodsman.  What would make a non-vented fly different than a vented.  It seems I get a visible roll out of the arrow with the solid blade that I don't see with the vented.  I have tuned the arrows to the bow and have matched the head weights as well.  Any thoughts would be appreciated.

Most of my roll issues have come from misaligned heads.  It shows more with a non-vented head cause they grab more air.  Helical fletch helps more than offset or straight.  It can also be from a combination nock and spine issue, altho you say you are well tuned, so that shouldn't be it in your case.

I only tried a non vented head once and it planed and that was it for me. I really didn't give it a fair chance, But my vented (woodsman and snuffers and 2-bld magnus) work great so I dont mess with what works.

I have shot three blade vented heads since Snuffers arrived on the scene then went to Woodsmans.  Both shot great with good penetration.  Last year I switched to Ace heads and they too flew extremely well and the penetration was much better in my opinion.  "Sometimes", you might have to play with another arrow spine to get the flight right.  I shoot 2016's without the broadheads and 2018's with broadheads for hunting.  The 2018's don't shoot quite as flat as 2016's, but fly perfect.  Something I did not do with vented broadheads.  Only a suggestion that worked for me and good luck.

Just non vented for me...................

Take another hard look at your arrow tunnig process.

If the arrow will shoot bare shaft with the same weight field point as the broad head, then it will fly just fine providing the following criteria is met.

1. The broadhead really is the same weight. Weigh it and the field point to prove it.

2. The broadhead is mounted straight.  Spin check for a test don't accept any misalignment.

3. You have enough helical in the fletch.  Use a full helical and perhaps full offset as well to spin an arrow with a realy big non vented head.

Remember you can steer an arrow from the front as well as the back.  When the arrow leaves the bow it is bent in paradox and you need to get it spinning quickly to avoid that initial bending to allow the broadhead to steer the arrow off course.

If your vented heads are hissing,and they are mounted straight, I would say that it still points to tunning.  

A vented head can have slight flaws on construction or might just need to have the inside edges of the vent de-burred or rounded.

Airflow that is smooth does not hiss.

If the Non vented heads are plaining or rolling they are not aligned properly or the arrow is not tuned, or you don't have enough helical on the fletchings.

I Shot a lot with Snuffer's and woodsman but found them to be a little noisy in flight but the biggest reason i stopped using them was the vents reducing penetration, splints of bone etc getting caught in the vents, sure i still killed what i was hunting with them but the Non vented head holds many advantages over the Vented.

I know a lot of guys still shooting vented heads with no issues,
but from first hand experience shooting a lot of Game with both, the Non vented heads Perform better!

Having no issues shooting a 1 1/2" non-vented 3 blade. No minor adjusments were required after bare shaft tuning.

[ALDO]

Thanks for all the input.  I will try a few one at a time, but I will start with fletching.  My bareshafts are good but I only use a 3.5" fletch with off set.  I have some 4" that I will try with a harder helical and see if that works.
Thanks again.

Shoot what flies the best....I think this worry is way down the list.....I've killed 95% of my animals with non vented zwickeys.....make sure your equipment is tuned and worry more about your shooting than vent or no vent. Best of luck to you in the field.

2-X What Terry said.

[Fletcher]

Aldo, start with the easy stuff first.  Re-check point alignment with a very critical eye and shoot them through paper from close, like 6 feet.

3.5" fletch isn't much, everything will have to be perfect.

[Joshua Grimshaw]

Also use Zwickeys, no vent and fly great.

[Fischman]

Vented heads always were noisy for me, now only non-vented solid BHs. Like others said tho make sure they are tuned perfect.

[Charlie Lamb]

Definitely try more fletch. I like to think that my bow is perfectly tuned, but I still prefer 4x 4-3/4" feathers to set this broadhead spinning toward the goodies.  
Magnus I w/bleeder. Main blade is 1 1/2" wide, Bleeder is 1 1/4".
   

Been shootin these through critters for close to 30 years.

[Charlie Lamb]

Here's an overlay of a Woodsman 3 blade vented and a Magnus I.
   

I can shoot these heads one after the other to the same point of impact and both kill stuff real dead.

[CRS]

I use both vented and non-vented two blade heads.

My two favorites right now, are the Eclipse and the Bear Razorhead screw in.  Depending on what weight I need, woodies or carbons etc.

I tried unsuccessfully to use three blade Snuffer's, Woodsmen and G3's.  Arrows were tuned perfectly and still heard what I deem uneccesary noise.

Shoot whatever flies true & quiet out of your bow. Shoot what you like and make sure they are scary sharp.  Of course, the most important factor is to put them in the right spot.

I am intrigued by the new Werewolf, as it seems similar to the Bear Razorhead, but just a much higher quality product in the weights needed to ge a little more weight up front.

[Montanawidower]

Can you really hear a whistle..... damn, I have shot too many guns in my life.

[ALDO]

Thanks again for the responses.
Jeff, yes I can hear a whistle but I had a great year and don't think any of the deer heard the Razorcap whistle.  I just wanted to try these solid 3 blade heads.  I like the profile a lot and there have been a lot of good threads on their toughness.  I will continue to re-check my set up and if I get them to fly they will be on my arrow next season.
Thanks

Aldo,
That should be one of the easiest broadheads to tune as long as your set-up is correct. Just go step by step in the direction the others have said. What weight are you shooting?
