Please clarify whether the ATF rule for LEUP only applies to APCP motors.
How about sugar & KNO3 motors or KNO3 composite motors? I enjoy making my
own motors. Can I switch to KNO3 or Ammonium Nitrate motors and not have to
deal with the 62.5 gram rule? Or does it cover any propellant... I can't
get a LUEP where I live.
