Per the OP's desire for a lever action, consider the Browning BLR in stainless steel, .243 or 7-08 topped with a Leupold 6x42 in Tally L/W rings. Box mag feed so one can used pointy bullets. SS so it wont rust. Could even go traditional and mount a peep sight to lengthen the sight radius from the OEM irons if the added ocular benefits of glass isn't crystal clear. Either caliber will ballistically overshadow the 30-30 by a decisive amount.

'Course a Kimber Montana in the same caliber wouldn't disappoint either. Go fondle both....
