.72 Kodiak/Minnie question

Hello:

I was wondering if anyone has treid a Minnie in a .72 Kodiak double rifle? If so, and it worked, where did you find the mould??

Just curious. I think that a Minnie in .72 would be a real stopper for those mutated Test Site Jackbunnies that we have running around here.

thanks all..
