Results of tuning:

Change C13 to 1.6n

Add 100R between Q1 gate and U6 output

Upon further simulation and testing, the following arrangemets ensure stability across a wide range of inductive loads.

Change C13 to 220p, change resistor between Q1 gate and U6 output to 750R, add seires 22R and 2.2n snubber to Q1 drain.
