EFOC in flight

[James Harvey]

#6881

I got some photos today that I thought were kind of neat of my EFOC shafts in flight. This arrows details are:

Total weight: 740 grains

Head weight: 440 grains

FOC:~30%

Shaft: 29inch .300 carbon

The bow is a 60# Samick Sage.

What you’re seeing here is a shot at about 9 yards. I’ve drawn a line from the head on the bow through to line of contact on the target. It’s neat seeing the head tracking down that line in spite of what is going on at the back of the shaft. I’m going to try to get to the range this week and see if I can get the same kind of shot at 20 yards to see how it all tracks over a longer distance.

Apologies for the flinging bow arm on release. An ongoing problem 😳

And close ups:

Very cool. I’ve noticed the same thing, particularly in breezy conditions. Why steer from the rear when you can drive from the front? 8)

did you have a cross wind? I can see the arrow in paradox, its the last pic that i see it tail right. You sir are brave. im gonna try and record my flight as well. something tells me that the cell phone is gonna get hit.

Thanks for the photos you gave me a real good idea..

S.T., no substantial cross wind. In the first frame after release you can see the shaft flexing one way, then in second frame after release it flexes the other way, even more substantially, with the nock right. One of the things I want to see in a longer flight is if how quickly that settles down. I would anticipate that the shaft would straighten out substantially over the 5-10 yards subsequent to that second frame.

It’ll be interesting to see. These shafts bare shaft tuned very nicely to my eye once I built out the strike plate a little, but I never thought to look at them like this bare shaft.

The safest place for that camera with me shooting is probably the bulls eye 😉

If you didn’t have any cross winds then I’d say your arrows tuned slightly on the stiff side. If you built out the sight window, you can decrease the build out and bring the tune into alienment.

Still, like the way you managed to get the pics of the arrow in flight.:D

Damn you fellas, I was happy to pay off that nock right as a crummy release on that shot, now you’ve filled me full of doubts and I’m going to have to go recheck the bareshaft 😆

Sorry 😆

Some say being slightly stiff with field point will be fine once the broadheads are installed.

Guess you can say the camera could be our worst tool. It will show what we can’t see with the naked eye.
