Ahaaaa! I just found out that 1:24 twist may actually be a 1;48 twist!!! That would be better for sure... I hope to get a confirmation on this from my friend soon on the actual twist rate of his 50 cal Kodiak.

By the way, I was investigating the Kodiak Safari Express double rifle muzzleloader by Pedersoli and it is a .720 caliber and it is a 1:75 twist!!! Just as you contend, Daryl, if you want to go for the big nasty ugly game, increase your bore size and go with a bigger Round Ball!
