Tuning Question

[J. Holden]

I'm shooting a "new" used bow trying to tune it.  I've never really had a problem with this sort of thing.  I've shot arrows that were recommended and it's been good.

The arrows I'm shooting are going where I want them to, at about 6 yards away, but the nock end of the arrow is going left as it enters the target.  Is it me or is the nock point on the string?

I'm shooting a 50# @ 28" recurve, center shot.  I draw it to 28" and am shooting 2216 alluminum's 29" in length.  I have 125 grain points with 26 grain glue on adapters on them.

I don't have money for new arrows right now.  So if it's an arrow issue can it be fixed with more weight up front?

Oh, I shoot lefty.  Thanks for the help.

You are definitly overspined. A 2216 spines out at about 73-74#s while a 2016 spines out to approx. 52#s. They either need one of three things, replace the arrows which you say is not an option, make them longer and add more up front weight, or add more weight to the front end to weaken spine.

Thanks cbCrow, that's what I was looking for.

58, to help in the future find the deflection of shaft(Easton) than take 28"/amount of deflection= spine rate.

hmm...I have a 2216 in the 80's (doesnt mean my charts are right lol).   showing 86 for the old ggII's and 84 for the xx75s.

According to the Easton charts deflection for a 2216 is .376 @28". 28/.376=74.5 #s.This is for the XX75's and XX78's. This is at 28" draw, if you pull 29" just put the length of draw on top than divide. Will get you close. I was taught that for every inch of arrow past your draw add +3# to spine. If you do the math its real close.

It can definitely be fixed with more weight up front but it will take a lot.

I had some old,29" 2216 arrows sitting around and one day I decided,just out of curiosity,to see what it would take to get them tuned to one of my 50# bows.I found that 250 gr points were too stiff and 300's were a little weak but shot pretty well.If I had wanted to use them,I would have made up some 275 gr points and I bet they would have been close to perfect.That would make a 685 gr arrow.That may sound like a lot but I shoot carbons that heavy all the time.You might be surprised.

I don't tune that close but start at 15 yds and move back as it gets dialed in.I want Fletched,bare shaft and broadhead arrows to all group together at 30 yds.Then I know I'm tuned and can hunt closer.

If you want more standard weight arrows,you need 2016's with 125 or 145 gr heads,depending.

If you want to play with what you have,start with 250 grs and be ready to go to 300.You can use steel adapters and glue on field points to make custom weights in between.

two different spine testers....weights and distances, two different deflections.   26 vs 28 centers and 1 1/2 vs 2lbs weights.

never understood why there's a difference...

[cbCrow]

AkDan, I would not have known it but was looking at the charts just the other day and saved them.

[JamesKerr]

You definately need to go up in point weight. I would think you would need atleast 250 grains (probably alot more) to get them tuned in.
