I've had the old 45-70 in for 6 or 8 months now and here's what I've found:

Pros:
-for a 45-70 it shoots softly due to weight
-accepts Weaver 63B mounts
-More accurate than I expected
-smooth lever function
-the receiver and wood are beautifully finished

Cons:
-IMO, if you want to reach out accurately you will need an optic due to the factory sights.
