What is the best all around bullet for a 45/70 guide gun. I picked up a 18.5" stainless non-ported from a guy that said he bought it new about 6 years ago.

I have dies and I'm about to start loading for it. Looking for a bullet that'll expand on deer and still hold together on elk sized game. I also may end up carrying it around in bear country.

I was thinking of the Hornady 350g flat point. Is that a good place to start?
