Lever action rifles have been part of America's hunting culture since the late 1830's. I'd say more black bears and whitetail deer have been taken with a .30-30 than any other cartridge could claim. The .45-70 one of the cartridges used to very nearly drive the plains bison to extinction. Even today both of these cartridges have dedicated followers. In the eastern US you'd be hard pressed to find a hunting camp that doesn't have at least 2 or 3 old .30-30's still putting meat on the table.
Out west the .45-70 has made a name for itself as a time honored bear defense round and in Maine it has a cult following among moose and black bear hunters. It's one of the most common hunting calibers in Alaska for moose and grizzly bears, even on Kodiak island where the brown bears have been recorded at 1200 pounds.
*Despite their proven effectiveness * they are among the weakest and least used weapons in the game. They were in the game when it first released, but they aren't even worth carrying most of the time these days. The Moradi effectively replaced them and they are restricted to one single scope.
The Coachmate has a flat top receiver, which means it is fully capable of mounting any of the rifle scopes or red dot sights available. The Whitlock could easily mount scopes and red dots over the barrel, effectively covering the rear sight with a rail to mount optics.
The vast majority of hunters using a .30-30 will take game weighing between 100 pounds (young whitetail deer) up to 500 pounds (average black bear in the eastern US) so it's much better suited to 3-7 class coverage. The average hunter using a .45-70 is typically hunting game between 500 and one thousand pounds (moose)
I'd also suggest a modernized .30-30 Lever action, the 7mm Regent has the Empress, the .270 Huntsman has the Warden and the Stradivarious. My suggestion is a .30-30 Explorer. It comes as standard with stainless steel and a laminate stock, essentially the big brother of the Moradi.
