I have the pmav take down recurve.
54@28. I am drawing 27 3/4 and have a 2216 tuner shaft. Here is what I have done so far. I cut the arrow a 1/4 inch at a time until it flew some what good. I ended up with a lenght of 29 inches with a 250 tip and still was a little knock right between 5-15 yards.I started out with a 145 grain tip and went all the way up to 250!!! My brace height is 8 3/4. the nock is 1/4 inch above center right now.should I go to a different shaft?? :help:
Oh yeh 1 more thing, I would like to be in the 600 grain range
Don't get carried away, I personally would be shooting a 2016 as you and I have nearly the same set-up, but make sure your nocks aren't too tight.
How is the arrow looking before it gets to the target? I would suggest that you try to shoot on a level plane, in other words make sure the target butt is at the same height as your bow, if you are shooting downward and you are not directly in front of the butt, it can give you a false reading. Ken Beck stated that a little nock right or left is not a bad thing, do you cant your bow when you shoot?
I think from what you stated, you are on the right track. I will be in the woods Sat. and Sun. let me know how you fair this weekend. See if you can borrow a 2117 or 2016 cut to the same length and let me know what you think....Scott
I'll try and explain how bare shaft tune.
I shoot a PSAV 58" 55# @ 28". I draw about 27 3/4 or so. My shaft of choice was and is 2117. My brace height is 8 1/4 and my nock is 3/8 off center.
What I did is I took 8 raw shafts and started at 29 1/2, the next shaft I cut at 29", then the next shaft at 28 3/4, and so on until I had all 8 shafts cut shorter by a 1/4".
Installed inserts and added 125 gr target heads.
None of the shafts flew good. So I changed to 145 gr target heads and tried again.
I didn't take long before I saw that a 2117 shaft
with 145gr target cut to 28 1/4 and 28 1/2 flew
near perfect.
All this was done indoors at 15 yds.
Next I shot the same 2 arrows from 20 yds and finally settled on the 28 1/4 for that widow.
I saved the arrows and have used them for 2 other bows in about the same pound range (57#-58#).
I hope this makes sense. I type with 2 fingers and sometimes forget what I want to say before I can type it out.
I'm sure others have members have different methods.......hope it helps you
Scott,
I do cant my bow. I put my target on top of the central air unit to make sure its level with me.
My arrow looke to be fishtailing to the right. (knock right) Do you think my shaft is to heavy then?
If you are shooting right handed your arrow is too stiff. You can lower brace height or increase tip grain weight, or longer shaft, or (lol) switch to a lighter spined test shaft. If I already found the sweet spot for a given bow I always switch to a lighter spined test shaft until I get it right.
When tuning never accept nock right, in my experience it creates headaches when shooting broadheads.

"target on top of the central air unit"-I KNOW what would happen if I tried that. Hap
Um, I have a question---if you are going to fletch the arrows, why not tune with fletched arrows?
Your certainly not going to hunt with bare shafts, right? Just a question..........I have an inquisitive mind.

jbiorn see the adcock bare shaft tuning method and you will understand...
for the bow, it appears that the 2216 is too stiff (0.376 deflection), if I were you I will try a 2117 (0.417) or a 2020 (0.426) shaft. the 2020 is an excellent caliber, its thin diameter allows a best game penetration with a very strong shaft.
Problems could be from nocks too tight, slightly inconsistant release (few are perfect), or many other variables.
Thats why using the OL method is so good - it takes these out of the equation. Allows you to get a spine choice that you then can fine tune with fletching.

Look at the post above I just placed
OL Adcock method works . give it a try

Ok, I'm a little clearer now----thanks. And sorry for hijacking the post.

frassettor. I have some 2117's im not using, send me a pm with your address and i will mail 3 or 4 to you.
P.S. 2117,s with 175 to 250 up front should get you your 600 grain weight
Use OLs method to try that type of bareshafting you would need a near perfect realease and very and I mean very consistent material to shoot into. I am sure like others said you are too stiff. I would try a 2020 cut to around 29"s and 125-150 point weight if ya want to shoot aluminum. Shawn
