+
+4 Terry-length Everyclear grains for 54mm cases, with 0.5 inch cores, 
+cast as two 6-inch-long double grains then cut and trimmed.
+
+This was my first time mixing APCP propellant.  Used the 4.5qt mixer and
+hand packed with no vacuum processing.  The formula was taken from a pdf
+about everclear, modified by me to use PAPI as the curative.
+
+These grains were cast on 2019-01-07.

+The batch size was too small, there was about 1/4" of the second casting
