You have to pay close attention, do some homework before buying reloads. I guess if you don't see the word compatible on the reload it isn't. Example of confusion: AMW 640 motor - AMW reload 4 delay o-rings used placed around the delay grain seated at the bottom of the grain. Kosden AMW compatible reload uses 3 delay o-rings placed around the delay grain seated at the bottom. Kosden TRM 640 motor uses 1 delay o-ring placed on top the delay grain. Jeff
