I think they would be higher caliber if left in their shell casing of a muffin cup. Or any muffin with nuts in it, that explodes into tiny almond shards before impact...
Clearly we're going well beyond desserts that are used for sporting, self-defense, or collecting purposes here. I don't have any problem with regulating the use of "destructive devices" as defined by the BATF (Bureau of After-dinner Table Fare) to include armor piercing muffins, large capacity pudding containers, PEZ dispensers machined for sound suppressors...etc. We do have to use a little common sense, after all!
Great, I can see it now... the government will want to regulate the sale of pudding and require complete background checks.
