The stats are in from the recent Graveler II rocket motor test by USCRPL,

It was a beautiful day on Saturday, Feb 17th 2018 when GRAVELER II, an 8-inch diameter, 80.5-inch long R-class solid rocket motor, was successfully fired, becoming the the largest successful composite case static fire by an amateur group based on total impulse! The motor delivered a total impulse of 42,000 lbf-sec,producing a maximum thrust of 4864 lbs.

Of note,

Graveler II, short for “Ground Traveler,” was a static test of the rocket motor for the upcoming Traveler III space shot rocket. This test was a key milestone in the development of Traveler III, validating the motorcase and nozzle design while also providing important data to characterize the performance of the rocket motor.
