They all don't shoot as fast.

This dart must have had a perfect seal.

Encouraging if it is real!

How did the shot feel? Is the program really that unreliable? If you where to use stereo, left channel at the front and right channel at the rear do you think that would be accurate? Or cause a delay of some kind?

Are we there yet? :P :twisted: :shock:

The shot felt fast!

It's not the program that varies; the tails sometimes blow open.

There is a balance between strength an weight.

Do you think recording in stereo will cause a better recording or worse?

A few more shots today at 200 psi.

Nail dart is a 3" 10d nails + tail weighs 109 grains

725 fps (127.5 ft-lb), 526fps , 625 fps.

It's the tail that matters.

The fit is the main concern.

I am going to breech loading so that the cone goes in point first.
