Hi guys... Got a quick question for you..
My setup is flying perfect with a buzz cut 125 gr. head on it... Perfect..
Just for kicks I tried a 125 gr. 3 blade muzzy...
My arrow hits low n left consistently.. From 15-30 yards every time...
Why ? I paper tuned, bare shaft tuned and broad head tuned.
I left the paper tuning and the bare shaft tuning, both a little weak, so when a bh was placed on it, it would be perfect...
What is a good explanation for muzzy's hitting left and low?
I also used stu's calculator and my set up is within 1/10 of being spot on...
Thanks
Steve

2nd question...
Would a 125 gr. wennsel elite do teh same as the muzzy?
Hate to buy a whole pack and them not fly like the Buzz cuts...
-
I don't have a good answer for you, but Buzzcuts are great.
-
Broadheads can all fly differently; not only due to aerodynamics, but the size and center of gravity is different. Sorry, but there is no way to tell if one broadhead will fly like another without actually shooting it.
Question for you though. If you have a setup all tuned and working right for you, why change it during hunting season?
-
My hunting hasn't started yet... My wife is expecting soon and I promised her I wouldn't go out until the baby is delivered! Do buzzcuts leave enough blood on ground?
-
My thoughts also,if the buzzcuts fly great why not use them?
-
May consider adding 1/8-3/16" to the brace height and then giving both BH's a go.
If that modification gives you positive relsults, then it may be possible that the nock pt is w/i ~1/16" to put them both spot on.
Just a minor change to discern a possible marked improvement.
-
Not sure I want to mess with the set up, just curious...
Have any you guys used a buzz cut to shoot a critter? How was the blood on the ground?

I used one just yesterday. Looked like someone painted the ground red. I used a 125 4 blade.
I've used them with both compound and trad bows. They work great.

Cool! Thanks guys.

When you bare shaft tuned, you left the arrow a little weak, but when you placed the broadhead on it, the broadhead doesn't stiffen the arrow. The broadhead weakens the arrow more because of the broadheads longer length than a field point. You're assuming the broadhead makes the arrow stiffer and it doesn't.
Also; although you didn't state it, Buzzcuts come in 2 blade and with a bleeder blade, 4 blade configurations. The Buzzcut you're using is probably a 2 blade configuration and if it is, the Muzzy is a 3 blade configuration. That extra blade with the Muzzy will make a difference to an arrow that is already weak by bare shaft standards.
And the nocking point might also have something to do with it. I shoot both 2 blade and 3 blade broadhead configurations with my recurves and both configurations hit where I'm aiming at. My nocking point is 5/8" high.

Did you spin the Muzzy? Just a thought that you could have one that is not right. I have shot the Muzzy heads for many years and only had a couple that did this exact thing and they were the 125's. I even think they spun ok, but never shot right. I have one on my bench now I have tried to get to shoot many times.
I think the whole thing about a broad head stiffening the dynamic spine or weakening it depends on the head. They are not all the same. I think 3:1 vented are longer and move weight out, but non vented has more weight at the wide part of the blade so about the same as field points for me. Two blade heads are also different and not always all that long. Seems like the buzz cut is a little shorter. The Muzzy also has an aluminum body, vented, and steel tip. Could be it moves enough weight forward to cause this.
I am shooting the 145 Elite. My tune is a little weak, and I thought the head wouldn’t work out. A 125 would be about right, but the 145’s fly great. The VPA would be my choice as it is non vented, has more weight back and is not all that long. Should shoot like your field points.
-
I'm shooting the 175 Terminator & Elites and they fly exactly the same as my field points. They're solids.
-
Nope, broadhead does stiffen an arrow a tad not weaken it. OL Adcock did a bunch of testing and the BH stiffens a shaft slightly. Always as bareshaft weak and feathers stiifen it well. I agree about spin testing the muzzy, may have a slight wobble. Shawn
-
I didn't write me no book :D but I've seen a broad head make an arrow act weak a lot more times than I've seen one make an arrow act stiff... although I have seen both reactions...
I will however agree that adding weight to the back of an arrow will stiffen the reaction.. .
What I think happens is that the BH exacerbates the borderline spine of the arrow.. an arrow which is borderline weak but displays well with a field tip will react weaker with a vane on the front of the arrow.. while a borderline stiff arrow will display as stiff.
I also believe that the surface area of the BH will determine the extent of that reaction..
-
Did you weigh them?
-
Yep... Weighted em...
THink it is just a bh that was bad...
-
i messed around with this for a while. I shot a few broadhead models and they flew different, some gravity and weight, some not made to spin right. I now shoot my arrows, mark them. Take my best ones and put broadheads on them, shoot them. the ones that hit where I want get sharpened and in my quiver. Others others set aside for other people. magnus, zwickey and ace never had a problem with.
-
I may be one of the rare ones,..but i have never had any muzzy's 3 or 4 blade trocar tip, fly well. They always grouped different then all my fieldpoints or other broadheads. This was in my compound days and before a fall away rest. I used to solve the problem by simply buying thunderheads screwing them on and have them hit the same as my fieldpoints. :dunno:
