You knew it would happen, after introducing the Taurus Judge in various barrel lengths to shoot .45 and .410 shotgun shells, they had to preemptively bring out an even bigger one, the "Raging Judge":
in glorious 28 ga. That's .54 caliber in case you were thinking of sniffing out some actual pistol-type bullets to go with this. I don't know of such a cartridge on the market, so I suppose you're reduced to alternating shot with slugs for variety.
Soon to appear, the "Batshit Crazy Judge", in 12 ga. Still in development it would appear.
Hmmmm.... Has anybody heard of anyone using a .410 Judge with slugs in a bowling pin match?
