The Contender did in 357, 44 and 45LC/.410.
The version I heard went:
TC brought out the .45/.410 with "de-spinning" choke and all was well for a while.
But then a dealer imported some cheap Brazilian .410 shot pistols with "scratch" rifling and chambers relieved to accept .45 LC.
The BATF shut him down for evading the regulations but had to include TC whose approach was previously acceptable.
So TC brought out the Hot Shot capsules in pistol brass and chambered the next generation of barrels to suit.
My neighbor the gunsmith bought a reamer and did a lively business converting .45 Hot Shots to .410, as did many other shops.
Eventually the Brazilian knockoffs dropped off the market and TC was allowed to resume selling factory .45/.410s.
Moral of the story; don't think the Feds don't know what you are up to with loophole evasions and don't think they cannot close loopholes by administrative regulation.
The bump stock is in focus now, I would not want to have money tied up in a Shockwave or "arm brace." They will ban them when they are told to.
