Hafejd30, I am with JTCrl, although it stands to reason that a .250 insert woodwork as well as any other as long as the hole is not bigger than .264 insert (whatever that is). It just makes no sense to me.

Grasping at straws, here, but maybe your original 140 A-maxes were not 140 A-max. I simply cannot believe there would be such a big difference from lot to lot. Even from decade to decade. I'd call Hornady.
