+# Test 2019-4 #
+
+This was a 3-grain 54mm Everclear motor using a #24 nozzle. Ignition was
+with one of Terry's igniters, on Saturday at the Tripoli Colorado Spring
+Fling event near Hartsel.
+
+The grains used were from the 21 May 2019 batch:
+
+* 21 May grain 5
+* 21 May grain 14
+* 21 May grain 7
+
+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.

+
+There was a fairly significant liner burn-through in the middle of the first
+grain near the nozzle, burned-looking area was dime-sized, with maybe 1/4"
+"hole" in the middle. Some extra ash on case there, but no obvious signs of
+weakening of the case. Not sure what that was caused by?
