Does this make sense? Update

[Buckeye1977]

I've been bare shaft tuning my new to me kwyk styk it's 47#@28. My draw is about 26.5. Brace height is set at 7 3/4. Started with some gold tip trad 500' s and they were showing weak all the way down to 28" with a 125 grain point and standard insert. Didn't want to cut them any shorter so I grabbed a gold tip hunter 5575 shaft from my compound and stripped the vanes off and started with a 175 grain point at 28". It was showing to be slightly stiff so bumped up point to a 200 and got decent flight but arrow seemed to be impacting about 4" to the right most of the time and a couple inches high. The bow seems to be very quick but I wouldn't have thought with this low poundage I would be getting good flight out of a 400 spine arrow. Was just wondering if anyone else has had the same experience and if I might be doing something wrong. Appreciate any help you can give me

I have two 47# recurves and two 45# take down r/d longbows that I use a GT Trad 500 arrow cut to 29" with a 175 grain point.  My draw length is just shy of 28" (maybe 27 3/4").  Of the 4 bows, two bare shaft dead on, one slightly weak, one slightly stiff, but close enough that I don't want to tune a different arrow for them.  All the bows are cut maybe 3/16" past center, with Martin rug strike plates that are about 1/16" thick.

With your draw length of 26.5", I would expect you to show stiff with your setup, so your results do surprise me.

Something sounds screwbally??? A .400 with 200gr up front should still be stiff. Have you checked the draw weight on a bow scale to make sure what is written on the bow is accurate?

No but the bow just came from jack and had weight reduced from 53 to 47# and he marked the bow himself. Not sure but seemed very odd to me too.

My 47# predator shoots a 390 ACC with 200 up front perfectly. But with my 50# bob lee they are to stiff. I know Alot of guys use a 500 Around that weight but to me they bare shaft to weak.

[rraming]

agree - you missed something with the 500's, they will work

[Buckeye1977]

The 500's were so weak that they were hitting the target sideways most of the time. When I first shot it surprised the heck out of me when the arrow bounced off the target sideways! I'm gonna mess with brace height and shoot some more tonight and see if I can figure out what's going on. The bow pulls lighter than my 50# longbow so believe the poundage to be right but don't have any way to measure it.

[rraming]

Shoot the shafts you shoot with the PL in your signature - should be close

[Buckeye1977]

Those are the ones I was bare shafting with and they're not even close. Got me puzzled

[Car54]

Have you tried 250 and 300 grain field pts. to check to see if their not bouncing off the side plate(false read)...

[nhbuck1]

goes to the show the fun of tuning i cant get my bob lee 54 at 28 which is my draw length to even shoot a 400 spine arrow with weight up front, the most i can get out of 29 inch arrow is 150 grains up front it was very weird to me, went to a 340 spine a 30 inch arrow like a 250 grain head and flys good, let us know how it goes buddy

No I didn't but tried a 100 grain point and was a little better but to shoot my 175 grain heads I'd have to cut them too short. Was shooting some more tonight and played with brace hgt a little but didn't make a great deal of difference. The 400's flew pretty straight at 20 yards with 200 to 250 grains up front on a 28" arrow.

I recently had some tuning issues that yielded false weak readings. The tell tale sign was on my bareshafts yellow arrow wraps had black streaks on them from my calf hair side plate. Hitting target nock left sideways. Those were 500 ,went with shorter 600 and installed black widow thick,soft rest and side plate  and now I am tuned.

I had a Centaur a few years back that I could not get an arrow to fly proper out of no matter what. I changed the new string out with another new string made from a different material...bingo. I know it sounds goofy. But if all else fails try it. It was the case with me. Never had it happen again with other Centaurs but that string material and me just didn't gell.  rat'

I had similar weak spine results due to velcro side plate wearing, so I built it up and cured the problem. I sometimes forget to hold bow vertical with no cant  when bareshafting and this messes up the results.  Fletching the arrow stiffens the spine a little due to the parachute effect.

[Buckeye1977]

The 400 spine arrow was flying decent with a 200 grain point and would probably fly great if the shaft was a little longer but I didn't have any longer in length. When I put a 250 grain point on it was showing just a tad weak. Hate to buy brand new shafts if I'm doing something wrong but the 500's are flying so weak that they hit the target sideways. The 400 seems to just need a little tweaking to get it right on the money. When I shoot the 500's that are fletched and wrapped at 29" with 175 grain point they porpoise a little but hit right where I'm looking

There's just no way a 500 should be hitting the target sideways. Showing a little weak? OK, I could believe that - every bow is different. But that far off, I have to think there is something else at play here.

My thoughts also just not sure what it could be at this point. I had no trouble bare shafting the longbow in my signature and that was my first time trying it. I'm stumped

[riverrat 2]

Get yourself an Easton XX75 1916 and cut that dude down to 27.5" and throw a .145 head on it. Maybe a .175 head. I will say this as well..my son shoots a 45#curve and he has crazy good flight with a 1535 GoldTip carbon arrow with .145 up front and a 29"arrow. He draws 28".  rat'

The fact that you are getting such terrible flight from something that shouldn't be that far off, and that you seem to also be hitting high makes me think you may be bouncing off the shelf and sideplate. You may need:

1. more brace height
2. higher nock point

both are cheap things to try. Just do one at a time and see if there is improvement.
