I thought .45LC/.410 was the most appropriate for the picture. For 10” I also have a .22lr and a .44mag barrels. I mainly use it in carbine configuration with 16” tube: .22lr, .223, .30-30, or .45/.410.
I’ve looked at them to complete my “ultimate Eastern Hunter Carbine kit” however, the $600 cost has moved down my priority purchase list...
^ Thanks.
