I was recently gifted two reloads for the AeroTech 54/2560 casing. They are not in bags with any identifying paperwork and the original owner doesn't know what they are either.
All the grains are labeled "EC," with the (presumably) nozzle-end grains also labeled #6, #5, and #4, each with a successively larger core. All the grain faces are slightly concave.
Anyone know what these are? I've read through all the 54/2560 reload instructions, but nothing seems to match.
