I like 170 grain bullets, both cast and jacketed. I reload with Hornady, Sierra, Speer, etc. 170 grain is the heaviest of the traditional bullet weights and will generally provide the most power for large game.
Now, for purely nostalgic reasons, for a 40's vintage Winchester '94, I prefer vintage 170 grain Silvertip ammo. I will even buy old Silvertip ammo in bad condition that is no longer safe and dismantle it for the bullets alone and rebuild with period correct components. I examine and weigh the powder charges that come out to get a feel for what may have been original. Sometimes I run into 50 year old ammo that has been so well kept, I get this feeling that it's still as good as the day it was made, maybe even better than what they make today. You gotta have Silvertips, you know?
