Neglected to re-weigh grains after trimming and before epoxying into the
liner. These were the pre-trim masses:
-* Grain 1, 590g gross, 574g net, trimmed to 4.5" long
-* Grain 2, 594g gross, 578g net, trimmed to 4.5" long
-* Grain 3, 592g gross, 576g net, trimmed to 4.5" long
-* Grain 4, 584g gross, 568g net, trimmed to 4.4375" long
-* Grain 5, 580g gross, 564g net, cut to 4" long
+* Grain 2017-7-1, 590g gross, 574g net, trimmed to 4.5" long
+* Grain 2017-7-2, 594g gross, 578g net, trimmed to 4.5" long
+* Grain 2017-7-3, 592g gross, 576g net, trimmed to 4.5" long
+* Grain 2017-7-4, 584g gross, 568g net, trimmed to 4.4375" long
+* Grain 2017-7-5, 580g gross, 564g net, cut to 4" long
Total propellant load thus somewhat less than 2860g.
O-rings made forward closure a *very* snug fit.
