I have the same gun, 1895 w/ 22" barrel. The recoil is not bad at all. Medium loads (like Hornady LeverEvolution) will not kick too hard at all. Those are fun loads, at 325gr.
Recoil is mostly a function of energy and bullet weight. A heavier bullet at 3,000ft-lbs will recoil more than a light bullet at 3,000ft-lbs. So the hot 405gr loads from Buffalo Bore will be your good ones for 45-70.
Recoil perception is merely a judgement derived from what you commonly shoot. As your recoil average goes up, your perception of it goes down, and you begin to actually shoot better. You can handle some BIG stuff that you might not realize if you work your way up to it.
For instance, a few years ago I thought that a .270 was actually a good recoiling rifle. Before I would shoot, my mind would remind me that "This is a powerful rifle". I would get uneasy and sometimes pull the shot. I have since worked up through energy levels, and changed views a bit. I now realize that the 17ft-lbs of recoil from a .270 is very small, and doesn't even really move your body. 300Win mag at 23ft-lbs is not much either. 45-70 with LeverE ammo should be around 30ft-lbs or so. 375H&H is about 50ft-lbs of recoil and it's not bad either if you warm up to its feel. 458Win mag is what starts getting attention at around 75-80lbs recoil. These are all assuming a 7.5lb hunting rifle. Regardless, these are all guns which I thought of before and imagined a severe kick that almost scared me just to think about. Now I realize that on the scale of things, none of them are anything to fear. They can all be handled without a flinch. Moving through these ranges I have allowed myself to shoot the smaller stuff much better than ever before, like .270-.300, simply due to my mindset on recoil.
The moral of my rambling: I think that if you want to use a gun for a hunting rifle but fear its recoil, you need to practice with a much bigger gun than the one you fear. Afterwards, the way you react to it will be totally different as you realize what it could be like.
Always keep a good scope eye clearance so that you are never afraid that the scope may hit you. This will cause flinch too of course.
