I'm going to go the other way. Get a big bore rifle. .35, .37, .45, there's just nothing quite like them.
And, they don't have to be elephant guns...
A .35 Rem in a Marlin rifle is a deer dropper, it works way better in the field than the paper ballistics indicate. .350 Rem mag (rare but oh boy!!) or a .35 Whelen (.35-06) they just flat knock critters down. Not as easy to hit at really long ranges, but you have .30-06s for that.
And/OR get a .45-70. Been dropping everything in N America since 1873 and is even better today thanks to new bullets.
Ok, not an easy long range rifle compared to an 06 or others, but a lot of fun to shoot, 400-500gr slugs just flat work, even at the lowly black powder speeds of factory loads, and the recoil isn't all that bad, until/unless you have one of the modern guns and start handloading the .45-70 up close to .458 win mag. Then it gets kind of punishing.
I'm really fond of my Ruger No.3s...have a .22 Hornet, a .30-40 Krag, and a .45-70. Great guns, nostalgia rounds and action, but the ability to load up to max modern potential, if desired.
