-this makes a 37% H-156, 208 Ns, with about a 1.2 sec burn.
+Coring rods extracted easily, new hickory tube caps came off without too
+much effort. Slight cleanup at the top of each grain since propellant always
+seems to fillet around the coring rod. Grain average fill levels looks pretty
+good, with on the order of 1mm space at the top as expected.

+Note that after casting grains and cutting a liner to 10.0", I realized I'd
+mis-measured the case, and we actually had 10.4" of liner/propellant length
+to play with! Fix this for the next time we make grains... For now, we'll
+fly these grains in a correct length liner and live with the fact that we
+could have put another 0.4" of propellant in the case! That'd be another
+13 Ns according to the simulator...
