RE: Deer rifle for small girlfriend
Help us help you, as they say. What's your budget for this project?
You can buy a nice used Savage around these parts for ~$250. Or a used Marlin, even with a scope, for ~$200.
My wife is quite petite, and she can handle a Marlin 30/30 with little trouble--and she really enjoys shooting my/our Marlin1894C in 357 magnum.
