I live in Ohio and they changed the laws this year to allow some straight wall rifle cartridges. I have a Marlin 1895 in 45-70 Govt. and need some suggestions for optics. The farm I hunt has a lot of open fields with ranges up to 175 yards or so. The reason I want a scope is because the old eyes aint what they used to be, and open sights are tough to see at dusk and dawn. I have a budget of about $350.00 or so. Considering a Leupold Ultimate Slam 3-9x40. Just wanted to see what others are using. Thanks.
