New arrow's not behaving like I thought...

[Oliverstacy]

I know that every arrow is different and tuning is always the best way to go but I have seen some strange things lately.  I'm in the initial phases of tuning and last night by floodlight was not the best conditions to do this.  I'm sure my neighbors love me shooting at 2 am in the morning.

New bow...55@29" longbow not cut to center, loves Beman MFX 500 30.5" with either 125 or 145 up front and normal inserts, they fly true with no problems.  

Wanting to shoot a heavier arrow I tried some Easton Axis 400 (non-camo) 31" long arrows and they fly great with 200 grains up front, problem is I never feel like I'm hitting anchor since they're 1/2 " longer than I'm used to shooting, these were test arrows I've had for a while.

For the record I have some 3 Beman MFX Classic 340 at 31" with brass inserts and 250 grain points that fly amazing and to where I look...but they weight 731 grains and are like shooting lead bricks.

I just got some Easton Axis Camo 400 and had them cut to 30.5" like my 500's that fly so nice...brass inserts like my other Axis shafts and they fly low right with 200 grain points.  They have to be weak but I think the nock point is fine since I can shoot the 500 and 340 to where I look with ease.

What am I missing...I've reloaded enough ammo to know that every 130 grain bullet won't shoot the same with the same powder load, tweaking is involved.

I have a limited amount of 170 grain heads and they fly better but a touch right...should I drop down more to my 145 grain heads...can there be that much difference in the two types of shafts (both Easton Axis, one camo...one not)?  I would have thought the .5" I cut off these arrows would have stiffened them up, doesn't seem to be the case.

Just some observations from an insomniac     testing stuff in the dark...by the way I shoot all summer and fall at night when I get out of work by floodlight so I'm used to that.

Josh, do you cant your bow?  If so a weak arrow will show low and right, how low would depend on how much you cant the bow...Mike

[Oliverstacy]

Should have added I'm right handed and I do cant the bow...that makes sense that if it was week it would shoot low right.

It was about 6" low and right on average...yet the 500's and 340's flew true.

You say they flew better with the 170 grain heads.  Try out the 145 and even 125's to see how they react.  Worth a shot...Mike

Don't know much about carbons.  If the shaft diameters are different, it changes the centershot relationship.

before you determine anything to be weak or stiff change point weight up and down and make sure they react accordingly.

A false reaction from arrow shelf contact will really confuse the stew out of anyone.

HI Josh,
We need to get out and do some shooting.I have found with my bows that .500 axis works great for bows around 50# with 225gr. up front but when i shoot 55# it seems i am in between .500s with light tips and .400s with a ton of tip weight.Chad

CHAD...R100 is August 22 and August 23 in Saginaw...are you up for it again?  Plus GLLI and Elm Hall I believe are the two weekends before the R100.  I'm planning on Compton this year also.

I love the way my 500's fly I just wanted to try 400's...I'm going to play around in the daylight to see exactly what's going on.

I'm going to do as R H Clark says and do the entire point range...I've done this in the past and it worked great.  I'll find what they like, just might take me some time.
