to say “you can’t” simply isn’t true. “you shouldn’t” is more like it
it is possible that Bill was shooting some .45 rounds through an old, thick walled .410 shotgun. Sounds like something he might’ve done.
Modern engineering has made modern .410 barrels far too thin to withstand the pressures of .45 long colt ammunition… but there are older guns that could handle it. Even with those, I wouldn’t recommend it… but again, it does sound like something Burroughs might do.
