ConclusionsThe acceleration curve did not spread out
The acceleration max value was not reduced
Ineffective at reducing felt recoil
Anecdotally it kicked more
Suggested Improvements
Instrument rifleLubricate current configurationPut springs in tensionDamper (screen door closer)Liquid (mercury)Particles (lead shot or sand)
