Test 2019-7

This was a 11-grain 54mm KNSB motor using a #? nozzle. Ignition was with one 45-cal pyrodex pellet on an e-match, on Friday at NCR North on Mile High Mayhem weekend.

The grains used were from the ? batches:

Small profile o-rings were used between grains, leaving the grains still slightly "loose" in the case. The buna-n o-rings on the nozzle and forward closure were lightly greased, and the liner exterior was heavily greased.

Results
