Do inverted gas checks work? I'm thinking of casting some dead-soft bullets to shoot out of a 10" 357 magnum Contender for a deer hunting load. It's a straight wall case, so there shouldn't be an issue with the check making it's way into the cavern of a bottle necked case.
I could size it first in a Lee push die. I did a search but didn't come up with any specifics. Thanks.
