Thanks for the catch - voice-to-type on my iPhone isn't always perfect.

Show me one single state law that REDEFINES a firearm classification, then we can talk.

What you outlined about the flintlock REGULATION does not change the DEFINED CLASSIFICATION of the firearm. It's still a muzzle loader, but PA REGULATES that only a certain type of muzzle loader is allowed.

PA isn't saying that a muzzle loader isn't a muzzle loader. They're only saying that a certain type of muzzle loader is allowed, and others are disallowed.

Shotgun only states are free to say "no brass cartridges" or "no rifled barrels" but that wasn't the conversation. Without a more specific regulation, a "shotgun only" law would NOT exclude a Savage 212 or one of Ed's 12ga from Hell rigs. Legally, it's a shotgun.

So again, show me ONE SINGLE STATE LAW that reclassifies a firearm - meaning a shotgun becomes a rifle, a rifle becomes a pistol, etc etc. that is in variance to the BATFE definition for that particular classification.
