I really like those little, more recent Weaver 2.5X scopes - which were discontinued a few years ago. I have been using them on a variety of more violently recoiling rifles for quite a few years and haven't beaten one yet. The 45-70 #1 was the first since I didn't want too much power and I like the eye relief. They are slightly larger than the Leupold 2.5Xs and have a slightly bigger, clearer picture than the Leupold.
