ARCH - Bounce Back

OK some personal observations and opinions.
What you describing seems like a dead-blow device. That device seems like
ot would have a jackhammer effect. It probably wouldn't bounce back as far
but it would transfer more energy to the target and hit excessively hard.
The energy has to go somewhere and either it goes into the target and
therefore there is little bounceback or it stays in the arrow and there is
bounceback. It think almost universally the head designs that have work to
reduce bounceback have increased the ouchiness of the projectiles. Also
please keep in mind that the amount of bounce -back, -forward, side, or
whatever is in a very large way influenced by the target with variables like
material (leather, metal, wood, flesh) and the angle of impact. These
variables change with every shot.
What many people and kingdoms call an ABD is a complete misnomer. They are
really nock-end Safety or Anti-Penetration-Devices. Big difference in
something that prevents bounceback and something that prevents the nock end
from penetrating a helm faceplate or reduce the damage a nock end can
Basically nobody is calling for a true ABD and I think that is good. What
people are calling for is a safer nock-end on arrows and bolts.

Subject: ARCH - Bounce Back
In discussing the problem of arrows "bouncing back" and possibly
causing damage through our helm grills, my brother said he had
seen devices to reduce bounce back which consisted of a movable
load which slid along the axis of the device. When the device
hit and began to rebound, the load was still moving forward and
impacted with the head absorbing most of the energy.
In our situation, that might be a blunt that was filled partly
with sand or a liquid. Or it might be a ring that slid along the
shaft. Is this practical?
Clearly it does not prevent deflections from causing trouble, but
it may help "bounce back" situations.
