JJPage, Never seen the Cabelas scope. However, I do like a scope for a lever action . 45/70. With Iron sights as a backup, scope primary sighting equipment. Now, if you plan on packing it in a scabbard like BIGNASTY does? Expect to fast draw from the saddle scabbard on a charging Grizz at 50'? That may require a different approach.
Backpacking creates no hardship with optics on a carbine as long as they are low profile and are rugged.
My old Marlin 1895 carried a steel tubed Lyman 3X with the standard #7 crosshairs. That scope is, of course, no longer made.
You need to ask yourself; Can I accurately estimate the distance out past 200 yards? Those hold over hashmarks are only as good as your range estimation. You have time to lazer it? No problem.
I agree with BIGNASTY on "you get what you pay for". A scope for that Marlin would need to be adequate for the handling, recoil generated and light gathering capabilities. It should have NO parallax issues and have no issues with the reticle. I have seen cheaper scopes with cockeyed/canted reticles and fuzz hanging off the cross hairs. Fuzzy edges around the field of view and other flaws that are aggravating.
IMHO, simple is the key. Quality is close at hand!
Buy one and inspect it. If you don't like it(don't mount it) send it back!
Another point is the scope mount. On that Marlin, use a one piece picatinny style base with the proper ring set. Lap them in to make sure them are parallel. Heres an example of the base;
EGW Marlin Picatinny Rail Scope Mount - 0 MOA. 47100. Evolution Gun Works Riflescope Mounts, Rings & Bases.
This will allow quick detachment of a damaged scope and rugged enough to withstand the recoil forces generated.
I hope this is helpful. I miss my . 45/70 Marlin. However I do have a big single shot . 45/70 that has taken its place. Just trying to figure out a good way to mount an external adjustment Malcolm style scope on it. Obtaining quality optics is the issue here! Have fun! GregH
