I looked up Super G Ranch. It looks very interesting. I'm considering going there too.
I'm a confirmed Handiholic, but despite my bias, I'd choose the Ruger .44 for a quicker second shot if needed if all she was hunting was meat hogs. I'm sure the Maxi would work as well, but is going to be a tad slower on the second shot. I'd use a solid bullet running hot in either. She needs to have a look at hog anatomy. The heart lung area is quite different than a deer and there's a substantial gristle belt to deal with.
If I go, I'll take my shorty .445 and .45-70 Handis.
