Depends, 7mm is too much gun up here. Most arhound here use 30-30. I would suggest 308. Seems your lookin at smaller cal. The 308 would probly give you what your lookin for. Unless you lookin for somethin real fancy, you can catch the savages on sale at walMart for bout $300.
.308 is a great caliber...If you want long range flat shooting the 25-06 or 270 aren't bad at all.
