Having had & hunted with both Ruger a #1 & a Ruger #3 in .45-70, I think a 500gr boolit in one will quickly persuade a shooter to drop down in boolit weight. .
Although YMMV, IMHO it was
MUCH more comfortable to shoot 350gr slugs out of those relatively lightweight rifles - especially the #3, with it's sharp/squared-off comb.
