Finding a rifle/cartage combo that is in current production will be the problem.
BUT There is the Winchester 1895 as used by Teddy Roosevelt. It has been made of late by both Winchester and Browning. The rifle was made in 30.06, 7.62x54R (Russian) and .405 Winchester. Additionally the Savage 1895/99 could be a candidate.
These are late BP early smokeless power rifles that will do the deed.. All capable of 200 yd elk shots.
Good Luck..
