Google "Winchester 231 being phased out" .
Short version is: Mfg can produce powders like tite group in a shorter period of time and want to phase out 231. However, shooters WANT 231. So, the Mfg is reducing production of 231, but not (yet) suspending production.
My suggestion is to use the powder you have, and enjoy it, but build your future loads on a more accessible powder.
