Reactive Targets?

Im sure a lot of people use the Steel Plinker targets, I do. But, I have been working on a new type of reactive target for high power PCP airguns.
I built the first one (starling) and put it 85 feet up on one of my towers to work on vertical shooting as I have a high miss rate.

It worked great and Im thinking others might be interested in them.

The targets are reactive (fold back the do a hard reset back).
I have only done the starlings but the mechanism could be used on any type including large targets like hogs.

What are people wanting in steel targets?
 
Here is a video of the first experimental target, The reaction force is variable, so if you use a larger round with more foot pounds of energy the reaction force is increased automatically, for the .30 and above the targets could be made from .25 mild steel.

My kids love to give the targets hell!

The others are all from Steelplinkers, the starling getting shot is mine.
So you know the impact force on this target, the .22 Monsoon is shooting JSB Exact 18 gr at 50 feet, 220 bar.
My 13 Yo loves the Monsoon .22!
