Also, for whatever it's worth to you. WHEN I scope my .30-30 it wears a Nikon prostaff 3-9X40. Right now my Marlin is open sighted. But I use that prostaff as an extra to bounce around wherever I need it. It's been on everything from a .22lr all the way up to a .338 win mag. And performs very well for what you would need.
I prefer the 3-9 option. In Pennsylvania we have antler restrictions and having that ability to get a slightly better look before taking the shot is useful at times.
I also see those on sale right now for $180.
