Draw weight and arrow weight question

[xsf1]

RadSav, I have a question for you.
You were talking about vaines making a big difference and I am a very technical shooter (I like to figure out the physics and stuff) so I am shooting blazers and I'm right at 290 fps shooting a 340 beman with a 100 grain montech. shoul I be shooting a different vains? I have read an article a while back but I didnt really trust it saying that a 4" vaine is what I want to be shooting.... so what is your take on it? is there any articles that talk about this?

Depends.  What length length is your arrow and are you shooting the ViBrake inserts in your 340's?

29 inches and no, however I'm thinking about switching to the easton injexion 330's which should be relitively close so the vaines should be the same.

I shoot a Rytera bullet-x set at 56 pounds

What about actual arrow length?  That Rytera have the Nitrous cam?

Assuming you are shooting a 28" arrow you should be good with that arrow combination up to about 65#.  If you are shooting the Vipro cam you should be good all the way up to about 68#.

If it were my setup...I'd probably shoot it with a slightly short arrow like 27.5" and set poundage at 65#.  You'd have a sweet easy to shoot setup with arrow speed around 270.   And then you would not have to change the arrows you have.

If you are shooting your Bemans with the Vibrake insert your FOC looks great no matter what fletching you have.  If using a standard 11-13 grain insert a 125 grain point may help you out a little if shooting 4" vanes.  Just remember that if you are using the 125 grain tip that upper draw weight will drop about 2 pounds.

The Bullet-X is not a real violent bow at 315 IBO(Nitrous) and 305 IBO (Vipro).  So I doubt you will ever want to go to the .300 spine.  I'd change to the .340 if I went above 67 pounds with that setup.  At 28" you will probably want the 125 grain point if you go the .340 ICS route.

No good articles that I know of in regards to this. 

General thought on fletching is:

Fletching Height brings your arrow into alignment faster while Fletching Length gets your arrow rotating sooner. 
The more mass in your arrow and the more oscillation your arrow requires to perform proper paradox the more negative force (drag) you want on the back end of the arrow.


At 29" in arrow length you are caught right square in the transfer zone between wanting height plus needing length.  It is also at that length where more often than not you will be wanting to go from a light 100 grain point to a medium weight 125 grain point.

I do not believe you are quite long enough to worry about 4" vanes on those reasonably light carbon arrows.  If you were a student of mine I'd keep you with the Blazer vane and make sure I fletched with the most offset I could.  This would be a great setup for using the Bohning Helix tower or jig.  Then I'd get you out to shoot those 100 grain broadheads in a good crosswind.  If we found they became a little "lazy" in the wind then I'd switch you over to a 125 grain point.

As far as the Injexion shafts...Just say, "No".  More money, more hype, less flexibility in accessories and really no real life advantages.  You will never see me stepping into the hunting field with those in my quiver.  If you are wanting a higher grade arrow than your Bemans go top of the line GoldTip or Carbon Express.  No real reason to change from the Beman though.  Unless you are like us seamhead junkies and just feel the need to mix it up once in a while.

thanks for the good info, I will shoot into a good crosswind and see what happens.

I shoot the vipro. So if I stay with my same arrows i will be good up to 65#? thats great news! Less money I have to spend the better. i was thinking about switching to the blazer 2" fletchings. I want to do it soon so I can dial in with them! Thank you so much for the info!

Looks like you might even get a bit more than that with the Vipro cam.  I'd set at 65# and get everything dialed in at 10 yards.  Then start to step the poundage up toward 70 about 1/4 turn at a time still at 10 yards.  Shoot three perfect arrows each time just to make sure you are dead on.  When and if your arrows start to walk to the right (right hand shooter) then back things off one/half  to one full turn and you should be good to go.

Good idea on the Blazers.  Make sure they are fletched with a good offset at minimum.  Max offset and Helical fletched even better!

Good luck.

Thank you so much for the information! Thats why I love this website so much!

If you shoot 100 grain broad heads you may get away with beaman 400s . my son shot them at 27.5 and 65lbs without any issues . I shoot carbon express maxima hunters with 100 grain slicktricks at 70 lbs and they fly very well anf impact with field points. four fletch blazers have worked the best for me .
