cant figure out these blems

[nhbuck1]

I cant get good bareshaft flight at all with my 50 lb bear, ive litteraly tried everything, i thought they were too stiff so i ordered some 500 beamens nope they are weak, i can get good flight out of the 3 rivers trad only arrows for that bow in 400 spine but the blems do not fly like bullets however i can get them too out of my bob lee can someone please help

Kyle,
From your post it seems to me that you are mixing three different shafts with two different bows.

Start over...
You need to find out what each bow needs by knowing the variations of each bow (individually) that would point you to a specific shaft to try with that specific bow.

If you can provide bow model, listed draw weight at a specified draw length and the "centershot" (the measured distance from the strike plate to where the string lines up with the center of the limbs when strung) many folks here can steer you in the right direction.

bear super grizzly 50 lb at 28 which is my draw bow is cut to center.

500 shouldn't be weak.

[nhbuck1]

there kicking tail left and impacting right

[nhbuck1]

Tony the bow is center cut the string lines right up

- BOP length of arrows
- Tip weight including inserts

[nhbuck1]

30 inches 175 grain head with 20 grain insert

"Generic" carbon 400s with the data you give are nearly perfect in spine.

Carbon 500s appear to be 15 dynamic# light for that bow.

Assuming 12 strand FF

It sounds like your Trad Only 400 arrow set up is the Arrow for you and your Super Grizzly.  

Maybe you can plug that information into the 3R spine calculating tool and then try to come up with a dynamic match for the Gold tip Traditional Classics? you are wanting to use.?

3R questions and answers for the Supper Grizzly put the Super Griz cut 1/16 past center.  the 3R spine calculator put the Bob Lees at 1/16 to1/8 past center, depending on bow.

Maybe you can use the 3R tool to do some reverse engineering from the Happy shooting combos you already have to come up with close dynamics for the shaft you want to shoot?    

There are many variables and then the Shaft Diameters are different also.

Agree with pinky, quit beating yourself up and shoot the arrow the bow is calling for.

Kyle you didn't state what the 400 Blems are doing stiff/weak?

The 500 you state are showing weak.  Build out your side plate to compensate and those will work.

What are you using on the 500? Point wt. and lenght?

All good questions!  I assumed (incorrectly) that the point weight and bop were the same.

the 400s blems are showing weak as well they all go nock left tried 145 to 250 grains 30 inch arrow

There was a post here recently relating to older Bear bows and the phenomenon we are discussing.

I'll try to find it and bring it up.  Perhaps it'll shed some light on this topic...

Kyle,
What is the center cut and draw wt @28" of your Bob Lee?

You' did not mention what brand of blems you are shooting. I won't mention a specific brand on this page either. But, I ordered blems a while back from a well know company. I assumed the blems meant that they were misprinted or discolored, not that they were poorly constructed. What I got was 10 correctly marked for spine. The other two were marked for the same spine but one was ten pounds heavier and the last one was 20 heavier. Additionally, when I spine tested them they varied in spine as much as five pounds when measuring them at 90 degrees and 180 degrees from the first measurement. I don't suggest that is your problem but it is something to consider.

this is only a year old bow

Kyle,

Ok are the 400 blems nock left bare shaft?  If so what is your impact point?  If it is impacting where your looking then fletch them up and shoot them.

Tail nock left or right doesn't matter it where there impacting.

If your getting a nock up or down then adjust your noc point to correct and shoot them..

i keep getting nock high i put a 250 grain head on bareshaft it curved 2 feet to the right vs the fletched
