I am aware of some of the letter designations associated with AT motors - 'A' = adjustable, 'P' = plugged, but is there a listing somewhere showing some of the others? I cannot find what 'G' indicates with regards to delays, i.e., G76-7G
 
But doesn't that normally come after the Newton rating? Like H128W-14A? The letter designation after the delay time usually indicated a property of the delay - adjustable, plugged, etc.. Does AT separate them to prevent confusion on the Mojave motors?

Also, if not designated as a delay 'A' (adjustable) can it be assumed that all Reloadable motors are adjustable with an RMS Delay Drilling tool?

Generally yes, but the G in this case is for Green. AT labels motors both ways. The other method of A and P are holdovers from the way Estes and Quest labelled motors, I believe.

AT uses S/M/L for short, medium, and long delays in the older non-adjustable products. Is that what you're asking about?

No, it was just the 'G' after the delay; it threw me off after seeing the propellant type usually listed immediately after the Newtons rating and before the delay. I just didn't want to receive a motor only to find it had some exotic delay that was not appropriate for my use.

Dang, Newbies and their questions, anyway... ;)
