# Batch 2019.05.21 #

8 Terry-length Everclear grains for 54mm cases, with 0.625 inch cores, 
cast as four 6-inch-long double grains with 0.5" delrin coring rods, then 
cut, cored, and trimmed.

The 54mm casting tube I'm using weighs 1.84g per inch.

Third time mixing APCP propellant.  Again used the 4.5qt mixer and hand 
packed with no vacuum processing.  Same formula as previous batches.

These grains were cast on 2019-05-21.
