You are definitely into the expensive exotic stuff ... which is okay for sure. But if you plan to stay within 400 yards shooting at animals (which to me is a stretch) I personally feel some of the suggestions are overkill. No crime in that for sure. In fact, if you own a gun that is overkill - and your Christenson tack-driver certainly seems to fit that bill - then maybe it won't look right with optics that are anything less?
I think red dot in a big scope is also overkill and may lead to taking unethical shots or shooting the wrong animal. If I can't see well enough through a conventional scope then it's probably too late in the day to be taking the shot, especially a very long shot. Right now I'm shooting a 3x9 Nikon BDC scope on a sporterized WWII 30-06 Springfield and I can get a 3" group at 300 meters (330 yards). 200 meters it's consistently just under MOA. Four years ago this scope replaced a 3X Weaver that the gun had worn since 1972. That old scope looked like it belonged on my gun and it worked fine tracking deer, elk, and moose in snow for up close and personal shots. But when in my sixties I resumed hunting big game on the plains of Montana and Africa, 3X wasn't enough to do the animals justice at the ranges I was encountering. It was a different way of hunting with eyes that had changed massively due to weak retinas. So appearance gave way to ethical considerations. I never messed up or lost an animal (with one sort-of exception) and didn't want to start at this stage in life.
I think the scope you have will probably do what you want out to 400 yards just fine (350 for sure). Perhaps others would expect to see something higher up the food chain on a gun like that. You decide what's important to you. And enjoy.
