I know that you mentioned "used" and a lot of people seem to offer the 30-30 as a good choice. I don't know your country, but I must agree with Supercub, ... what if a 300 yd opportunity was to present itself?
My suggestion is a Stevens 200 in 7mm-08. Very accurate, inexpensive, my daughter took her very first doe at 320 yards, bang, flop shot. For the close quarter shot, I suggest a low magnification scope like a 1.5-4 or 5 x 20mm, and it's still get you out to 300 yds when needed.
