What are your thoughts and experiences with the 45/70 for bigger game, like elk, moose, bear, bigger bear at modest ranges ?

I've only killed deer with my 45/70, and of course it worked just fine. But... for bigger, heavier game, what's your choice and why?

Commercial ammo, or handloads, either way.

Love the voice of experience, but also very interested in well-reasoned opinions.

Thanks! Guy
