I don't live in IN so all my info is second hand, but what I am told is that the rangers have a drop in piece set to over the legal case length, if the drop in measures too long you are busted, same for case OAL. I'm not sure what the law reads but it is my understanding that just changing the ammo is not enough, in other words I don't think it is legal to use a .460 revolver and only be shooting .454 in it, I believe the weapon itself has to conform to the law. Hence Coyote guns chambering the .460 short (not sure what he is calling it)
