Don't they sell a Thompson Contender chambered in .308? I know the come in .22 and .223.
I have always liked that Taurus Judge too. I know a woman where I work who has one and she loves it. She is not a petite woman, but still no RollerDerby Queen either.
She says it is not bad to shoot at all. I gues you can select the .410 shells you want to use in it. There are likely some lighter loads.
