Lever Gun Caliber choice Help

Basically, I need help deciding on a caliber for a new lever gun - and I need a little help fixing my stupidity. Here’s the facts:

I want this rifle as a host for my Obsidian 45. It’s going to be a general purpose carbine (16” barrel) for plinking, hunting, fun, etc - not defense. I hand load and intend to make everything from subsonic heavy weight bullets all the way up to full power hunting rounds. I live in Ohio and want it to be a straight walled cartridge for deer hunting. BUT… I may have the opportunity to use it on heavier game outside of Ohio (black bear, hogs, and a slight possibility for moose). I’m either going to put a red dot on it or a 1-4x trijicon. Figure absolute max range at 150 yards. Practical range requirement is more like 100 yards or less.

I already have one rifle (Older, not threaded Henry Big Boy) and three revolvers in 44 Magnum and reload a lot for them. I have one competition 1873 in 357. Furthermore, I have enough reloading supplies for 44 magnum that I can’t imagine having to buy more…maybe ever.

I’m currently leaning towards a Marlin 1894 SBL in 44 mag. - which I think is the right answer. I’d also consider a Henry or S&W 1854, but the SBL has everything I want right out of the box. Price isn’t a factor - I just want to get the right thing from the get-go so I’m not F-ing around with trying to make it right after the fact.

But I’m wondering if I should be considering a different caliber or bolt gun like the Ruger American Gen 2 in 450 bushmaster, or 350 legend, or even an Marlin SBL in 45/70 (this is what I’m really weighting against.)

I’ve always liked the idea of 45/70 - but it’s overkill for general purpose and I realize that. My powder and primer supply would work for subsonic but I would need new dies (lee is good enough), a source for plinking projectiles, and new brass. I think, if there’s an upside, my spent brass would be really easy to find at the range just due to the size and shape. Again, price isn’t a factor… what I’m really struggling with is the headache of managing another caliber. I already have way too many and time keeps getting more expensive.

Should I just stick with 44 mag, or should I consider venturing into the world of 45/70 (or another caliber)?

Also, thanks for helping me through my dumb ass struggle with rationalization…

I will admit to a little bias up front. I really like the 45-70 as a hunting cartridge. I own one myself.

As you already reload you would be able to take advantage of the fairly wide range of bullets available in .458. The Marlin action can handle some pretty stout loads, but obviously they don’t need to be. You should be able to find a load/projectile combination to suit your needs quite well.
