Sorry to hear of your misfortune, sounds like you got a lemon. Mine is an old Model-450, and I can't force the top punch to deflect enough to hit the die. The top punch and die holders should be dead-on coaxial. Lyman has been making lube/sizers for a long time, you'd think they'd have the process pretty much figured out by now. The remedy is Lyman's problem, don't make it yours. Contact them, or the vendor, for return authorization and instructions.
