I agree the numbers aren't that amazing. I wanted one when I first saw it, but only a few weeks later I'm having trouble thinking of a use for it... If I hunted out of a tree stand and didn't take shots over 100yds then it sounds like a fine choice, but I don't... And I don't like medium bore AR cartridges very much either, I feel like the 6.5grendel is about as big as you can go without losing too much velocity for my liking, unless you use bullets with dreadful ballistics and sectional densities. 450bm or 50beo would be neat for close quarters hog hunting but I don't do that either so... And as a hunter first and foremost, I see no reason to get something like that over the tried and true 45-70...
I did want a big and slow cartridge just to get some first hand experience with wound channels, how game reacts, ect to that vs the small fast stuff I typically shoot (243w, 270w, 7RM) but something like the 9.3x57 or 358win seem like much better options for that sort of thing - I'd be comfortable using either of those on moose, not so much the 350 legend...
