how much you want to spend?
vortex makes really nice stuff, Nikon, leupold.
I'm a cheapo so I go with Nikon prostaffs, and vortex crossfires. for hunting I like 3-9-40 or even a 50mm.
if it was me and I used the 30-30 to deer hunt I would put a 3-9-40-50 on it.
one thing my buddy told me the other day was get the higher powder because when you need it and its not there you will wish it was.
I will say this bushnell will never get another dime from me. scope broke from recoil and they wanted me to ship it there and back on my own dime and told me it was pretty much my fault. scope was less than 2yr old.
