I read in the "Cartridges of the World" that the .410 shotshell can be shot in any rifle chambered for 45-70
I also see guns that will shoot 45LC or .410 shotshells
Where can I find something that shows what can be shot in what.
I don't think that this is a very good practice.
I always adhered to the rule to make sure you use ONLY the ammo that the gun is chambered for.
