A lifelong Nebraska plainsman, I've never quite found the necessity for a bear or moose rifle. Sadly, bison were eliminated three or four generations ago. I've long cast a desirous look upon a .45-70, I never quite convinced myself.
I do cherish my early 90s Marlin 1894 in .44 mag. For me, a do anything rifle, especially as I'm in the east of my state, and typical ranges rarely exceed 150 yards. And with its magazine capacity and ballistic performance, a stealthy "social" rifle, if must needs be.
