i killed 2 big boar hogs back in september with my 45/70 and i used a winchester 300grain hollow point. Thats all i had and i figured it would not work good but it actually worked great. The first one was about 100 yards away and i hit him a little further back than i should have but he only ran about 40 yards. The other i got a better shot at and put it in his head, he just piled up on the spot. Both weighed over 200lbs.
