angle of impact is varying

[Pipefish]

Hi I have noticed that when I shoot from 5m my arrows seem to be impacting the target at different angles from their trajectory. When I back up to 10meters, they straighten out save for 3 arrows that are a different type than the others.

Could this be happening because of my release? The arrows are somehow coming off wobbly and on the longer shots they have some time to stabilize due to the fletchings?

Here is my setup if it helps explain this phenomenon:

Bow: 29# Ragim (L.L. Bean's starter recurve bow) the draw length is 28", but this may be short as my wingspan is 73"?

Arrows (all cut to 30"):
I mostly have Beman Bowhunter 500 (carbon 7.3gpi)with screw in target tips.
I have 3 Easton Genesis 1820s (aluminum) with permanent target tips.

At 10m the aluminum arrows all land crooked in the same orientation (their fletchings however seem to be matching up with the target).

I am trying to connect a picture to give a visual (the orange and green fletchings are the carbon arrows.  The white and yellow feltchings are the 3 aluminum arrows).

Thanks for your input,
Dan

Thanks again!

Another piece of the puzzle:
The notch on my carbon arrows are in such an orientation that I must have the odd-colored feather pointed down (instead of away from the bow as I was instructed).  On my aluminum arrows they are in an orientation that has the odd-colored feather facing away from the bow.

Pipefish,if your'e going to shoot plastic vanes you'll need to use an elevated rest.A cheap stick on flipper rest will work fine.Off the shelf you can use feathers.you can turn the nocks to line the cock feather 90* out.

Thanks shoothathang,
The bow came with a stick on flipper rest, so I'm alright there.  As for the nocks, I will turn them 90*, but now have to research how to do that  
Cheers,

Dan - just grab the shaft, grasp the nock between index finger/thumb, and twist till the index tab on one ear of the nock aligns with the cock feather.  It might be a tight twist, but it's simple.

You say they land crooked, but in the same direction....you don't mention whether they are tail right or tail left, if they're landing at point of aim or not, and whether you're Right or left handed.  You might want to go to O.L. Adcock's site and look at the article/tab entitled bow tuning...you'll find your answers there.  
Good luck
